I'm relatively new to having a NAS, running Docker, and immich. I've got a UGREEN DXP4800+ running UGOS and installed immich v2.7.5 when I first set it up a couple of weeks ago.

Not sure how helpful this is, but for noobs like me, and for anyone else who doesn't know, there's no way to edit the .env file in UGOS because UGOS doesn't show hidden files. I took these steps and successfully upgraded to v3:

1. Navigated to Docker's immich network path from Windows (in my case, something like \\UGREEN_NAS_NAME\docker\immich\).
2. Opened the .env in Notepad++ (any text editor will do).
3. Changed IMMICH_VERSION=v2 to IMMICH_VERSION=v3, saved, and closed it.
4. In UGOS, opened Docker, went to Project, Stopped the immich project, hit the 3 dots and selected Settings.
5. Went to the Compose configuration and hit the Redeploy button at the bottom.
6. Docker updated immich to v3.
7. Verified that immich loads correctly and does what I need it to do on my home network (hardwired desktop PC, and via Wi-Fi, laptop, iPhone, & iPad) and on cellular (iPhone).

Found a dude locally selling 4 14TB Seagate IronWolf for $120 each or all four for $450. Ad says no SMART reports, no CrystalDiskInfo, no power-on hour reports, no warranties. I PM'd him and he said he's had them for about 5 years. They were pulled from a working home NAS.

I was planning on getting my first NAS and was between a UGREEN DXP2800 (2-bay) or a UGREEN DXP4800 (4-bay), but if this is a risk-worthy deal on used drives, I may go for the DXP4800.

So I had it in my head yesterday to change the DNS on my Deco to Mullvad's DNS. Big mistake, because my personal iPhone, work iPhone, iPad, GF's iPhone, work Windows laptop, personal Windows desktop, two Smart TVs, and Litter-Robot all went offline (iPhone was still "online" but couldn't get to most sites and was still able to connect to Deco app; iPad couldn't get anywhere and couldn't even connect to the Deco app, which I had in the past).

I had gone into the Deco app on my iPhone, hit the More button at the bottom, went into Internet Connection, selected Internet Settings, hit DNS Address, changed it from Auto to Manual, and set the Primary DNS to 194.242.2.4. I hit Save, went back out, and everything stopped working.

While I was still connected to the Deco app on my iPhone, I kept seeing "Unable to connect to Deco. Please check the network status." banner in the app. I was able to go back in and change all the DNS servers back to CloudFlare's (1.1.1.1 and 1.0.0.1). Now, this is where it gets funky.

Most of my devices are working again. When I go into the Deco app, the correct DNS addresses are showing up:

My SmartTV stopped working (it's "connected" but is also saying there's no internet connection). On my SmartTV, the Wired connection DNS = Auto and is showing a DNS address of 94.242.2.4, not 1.1.1.1. If I switch the SmartTV to Wireless, it too shows a DNS = Auto and with a DNS address of 94.242.2.4, not 1.1.1.1. I manually changed the DNS addresses to both Wired and Wireless to 1.1.1.1 and my SmartTV has internet again.

My Litter-Robot refuses to connect, at all. So I logged into the admin site on my Windows desktop (http://192.168.68.1/), went to the Status page, and it shows a Primary DNS of 194.242.2.4, NOT 1.1.1.1 like the Deco app is showing:

I decided to unplug my main XE75 unit to see if that would resolve this issue and when it finally rebooted, the LED stayed red. I went back into the Deco app on my iPhone and the Primary DNS was back to 194.242.2.4! WTFF?! I made all of the changes, AGAIN, to get it back to 1.1.1.1, did a reboot of the XE75 again, changed the Primary DNS from Manual/1.1.1.1 to Auto, rebooted the XE75 AGAIN, went back into the Deco app, and the Primary DNS was once again BACK TO 194.242.2.4.

Periodically checking the Admin page on my Windows desktop, the Primary DNS remains stuck at 194.242.2.4. I finally got the Deco app to retain a Primary DNS of 1.1.1.1 (and secondary of 1.0.0.1), but it's making ZERO sense to me that the Admin page is still showing the Primary DNS as 194.242.2.4.

I suppose the last thing to do is a hard reset of all 3 Deco XE75's that I have (not only because my admin page is listing a different Primary DNS than the actual app, but because I can't get my Litter-Robot to connect, and every time I open the Deco app, I keep getting "Unable to conenct to Deco. Please check the network status.", even though I have an internet connection and my phone is actually working.

AmI missing something here, or is the Deco app just not working as intended?

EDIT: I should add that the ONLY way for my iPhone, iPad, GF's iPhone, GF's iPad, Windows laptop, and work Windows laptop to work is to manually change their DNS's to 1.1.1.1. Also, my cats' autofeeder (dry food) is now also offline and will not reconnect, presumably because it's being assigned a 194.242.2.4 primary DNS automatically.
