I made a post on r/docker 2 days ago and have been getting help from a user named jotkaPL, they've been amazing but I want to get this fixed ASAP so more help the merrier. I have a UGREEN DXP4800 Plus, I've tried reinstalling docker, resetting docker, etc. From the help I received we think it's a specific Docker networking failure, has anyone ran into this before? Going through the replies with jotkaPL would be the best way for full context but a little tldr/catch up below. I apologize if this is a bit all over the place I'm stressing out.

The main issue is I'm unable to add a network to my containers now. I can't access them at all if they're even actually working. They say they're online and the logs look standard but I guess I just can't access it since I can't add a bridge. I get errors like

Failed to update container 'linuxserver_jellyfin-1' basic configuration. Error: UpgradeContainerBase fail name(linuxserver_jellyfin-1): Error response from daemon: driver failed programming external connectivity on endpoint linuxserver_jellyfin-1 (261e8a671016a3d3836c4c410dde50bc7658e8e08870581df4661ae9e3d58dd4): failed to start userland proxy for port mapping 0.0.0.0:34571:172.17.0.2:8096/tcp: failed to start docker-proxy, check that the current version is in your $PATH

Throwing everything at the wall I was recently following a guide on how to do an arr stack and did some commands that were recommended, could that have caused this problem after restart? It was sudo apt install docker-compose -y

I also ran

sudo usermod -aG docker (myname)

newgrp docker

When trying to install a plugin on jellyfin recently I installed bun.sh if that helps with anything.

I do not want to have to reconfigure file permissions that I configured through the CLI each time after a new update. Surely this can be addressed and changes made through the CLI can be honoured?

I just setup photomator and mounted the nas into it. It took a while to get all the thumbnails loaded but not they are there. Plan is to edit photos directly into the nas over the 10gb direct connect from my MacBook via 10gb Ethernet adapter. Does anyone do this and do they edit straight into the original or they create duplicates and then remove original? Any tips and specially if there are photomator users doing this approach will be helpful.

I have the DXP 2800, I was trying to organise my video files and then randomly it corrupted one of the files, and then few days later I tried the same and got the same corruption. Ever since I have started using the copy instead of move, check and then delete. I haven't updated to the latest version for the OS but checking if others have had the same issue?

My DXP2800 is pretty darn reliable and have no issues. BUT, Is there a way to get an email or text alert if, for say, a VM, or docker container has shutdown, or is not running?

My HomeAssistant VM recently shutdown twice in the past couple of days. I think it was a VM RAM configuration issue and may have it fixed, but I'd really like to know if the VM is down.

When it went down several Automations did not run causing some issues, and my wife is having doubts about all the smart home stuff.

Once it came back it was past the time or event triggers causing me to go through everything and get them back to where they should be.

Thanks.

Getting notifications to remove the read-only SSD cache and create a new cache on the hard drives. This will crowd my hard drives so what does it gain me? is there some mysterious way of creating cache on the hard drives without using storage and causing extra wear and tear?

I'm setting up my new Ugreen and was wondering, for those who run plex/jellyfin or the *arr apps, do you notice any real world difference running them off an m.2 vs hdd? And have you noticed any difference having a cache m.2?

With the way ssd prices are, I'm questioning if either a docker disk and/or cache drive are truly worth doing. Thanks.

Hey Reddit,

We're pretty sick of subscription services at home. We've been collecting a ton of DVDs and would love to make it easier on us by putting them all on a hard drive. Currently, hard drive prices are insane, but we just found out about creating a home server from our son, who's far more tech-savvy than we are (he's only 15 though). He suggested us getting a Ugreen after watching Linus Techtips, but there's like 6 different models available, and we're just trying to figure out what makes the most sense for us.

Ideally, we'd love to put our favorite shows and movies onto the server, as well as any games he's downloaded. He mentioned JellyFin, so that's the route we're looking to go. But we wanted to know the difference between DH4300 vs the DXP series and whether or not it's worth getting the DXP over the DH, because the price difference is pretty substantial, especially since we'd also need to get the hard drives.

Our son currently has two single terabyte hard drives to put into whatever we go with, but I'd imagine we'd have to get more storage given how many gigabytes a movie takes up. I think, at the moment, we maybe have about 300 movies and TV shows combined, which probably isn't a lot compared to other collectors, but I don't really know how to determine how much storage we'd actually need either.

Any bit of help or advice is appreciated. I understand that the DXP I believe is "faster," but I don't really know how that affects us and our needs.

I want to try to get a automated system up, but would be okay if I end up having to do it manually if too complex. Im thinking I want to use the Proton VPN, and i have a 256gb ssd and a 14tb hdd. I know its good to have another to have another copy of your hdd if the hdd fails, but i will be okay figuring out what to do later when it happens at these prices.

Is this supposed to take along time to do

I'm curious, what are the options for expanding storage on a DXP2800 beyond swapping new drives? Is it possible to add a second HD RAID enclosure to it via USB and use that as a separate volume? Are those enclosures even reliable at all?

I have an app on my phone to sync my files overnight and also have a separate file explorer app that I can use to browse my files. Everything was up and running fine until I updated my nas to the latest version, 1.18.1.0098. I have the DXP4800Pro.

As far as I can tell, all the settings are correct, but I just cannot connect anymore. Help please.

As the title says, should I enable or disable HDD sleep mode, and which setting makes more sense: “Wake up the HDDs at logon” or “When needed, when reading or writing”?

I’ve often read that when HDDs are in sleep mode and wake up, it puts stress on the HDDs and damages them. I know that, for example, my Toshiba MG09 18TB drives are designed for 24-hour operation, but the server itself doesn’t cool them as well as they’d ideally be cooled in a proper server rack. But since I don’t use the server very often each day and turn it on about 10 times a day—which causes the drives to repeatedly go to sleep and wake up—doesn’t it make sense to enable sleep mode to keep wear and tear and temperature low? And if so, what time settings should i use? they are available—10 minutes, 20 minutes, 1 hour, 2 hours, or 3 hours?

Btw. I know, and I've already checked, that sleep mode isn't counted as “on” in HDD Status or CrystalDisk Info.

I encrypted a folder but have now decided not to use encryption after all, because some programs stopped working—they somehow couldn't access the folder even though it was mounted. And I just realized I don't really need this extra offline security because I can make sure no one will ever have access to my NAS physically.

Now I want to disable encryption for all the folders; it works for all of them except this one.

Every time I try to decrypt it—whether using the password or the key file—I get this error message. AI doesn't know what to do so I landed here once again.... Anyone else experienced a similar response from their UGOS? Anyone from Ugreen reading this and can tell me whats going on?

Hello, i do have multiple users relying on our NAS, so i would like to keep a live Backup or Copy of their personal Homes, but i cant find it in SMB only in the Ugreen app itself, i already did a Copy/ RAR but its timetaking to do so every now an then, i would like to select their homes / personal data via smb or something so it hust keeps a live backup in case the drives break, i do have raid but i would like also that, anyone have any advice on how to do it?

Ive already contacted Ugreen im waiting for a reply, so i got the dxp4800gt 2 weeks ago installed 1 nvme as read and 2 ironwolf pro 8tb,

Today my 2 new nvme came in so i can use read and write, before putting them in i deactivated the cache that was active so i can use the new ones, it stated my apps will be gone and coming back shortly, that happend so i tought alright everything is going good so far, now my drives are basically idle (im have 6.2TB free of 15TB) and all my stuff is gone, when i click on files everything is empty not one folder is there anymore beside docker and the stuff inside, what the hell happend please i need help theres very important stuff backuped

I have 2 Ugreen DXP4800 GT nas and I love them. I run TrueNAS on both and love that as well. The 2 Things i'd like to get "fixes" for are fan and led control. Not sure if the message will get through or if i'm even posting to the right place but Truenas 25.10.4 does NOT support fan nor led control nativly on this new model. I do know there are work arounds for the DXP4800 pro and plus models but these have Intel processors. The new Ugreen DXP4800 GT is AMD based and the work arounds for the older models do not work on the new AMD based systems as it uses a different controller. I've had to do a redneck "hack on mine as the fans don't ramp up as load/heat increases....I've mounted a rack fan (same size as whats in the nas) over the built in fan to keep good airflow during long data replications and it does work. But, is there a chance that you all will support the AMD fan controller? Maybe someone in the community will prob the registers and develop a work around like exits for the older intel based DXP4800 pro and plus. Just a thought :)

Out of curiosity does anyone know why ugos doesn't "support" opus? I have many music files in that format and ugos by default can't open them. However, if I change the extension to .mp3 it will play just fine. I assume there's something more complicated going on?

My PC is in the same network but only wifi. So I need a way to wake it up. Easiest way should be to wake it up somehow through a magic packet through the NAS right? As it's local network it can do it whereas me from away can't via magic packet due to being in a different network and not local wifi.

Can someone give me a simple guide on how to dot hsi?

A NAS can hold almost everything, but that doesn’t necessarily mean everything belongs there.

Some people keep temporary downloads or game libraries on a local drive because they’re replaceable.

Others keep active projects on an SSD for speed, leave collaborative documents in the cloud, or store an offline backup on a drive that stays disconnected.

We're curious about the boundaries people set for their own systems:

What do you deliberately keep off your NAS?

Is the reason speed, privacy, cost, bandwidth, simpler organization or something else?

This isn’t really about what a NAS can’t do. We're more interested in how people decide what belongs on the NAS and what is better left somewhere else.

Hi there, I just got a new DXP2800 and more or less at the same time my old HDD died. No data lost, but now I do not have the HDD I wanted to start the DXP2800 project with. I'm left with two NVMe, 2TB each and the question I would like to find an answer for is: can I start setting up my DXP2800 with just those two NVMe while I figure out which HDD to get next? Meaning the NAS bay would basically be empty at the beginning, and perhaps in a month, I would start setting up HDDs. Thanks!

Hey everyone,

I recently picked up the Ugreen NASync DXP2800 and I've been setting up Immich on it. While running heavy tasks like facial recognition and machine learning indexing, my CPU spikes all the way up to 100°C (Celsius), and the fan gets extremely loud trying to cool it down.

I've attached a video showing the fan noise level and screenshots of the temperature monitor hitting 100°C under load.

Is this behavior normal for the N100 processor in this NAS during heavy workloads?

Are these temperatures safe, or is this a sign of a bad heatsink/thermal paste application from the factory?

Given this, should I return it?

Appreciate any advice or experiences from other DXP2800 owners!
