Unraid 6.12.3 has improvements related to IPv6 https://forums.unraid.net/topic/142116-unraid-os-version-6123-available/

Hmm, just to simplify the system, try removing Tailscale and then please provide updated diagnostics

Rename the `extras` directory on your flash drive to `extras.old` and reboot. There is probably a conflict with one of the files there. If that doesn't help, start in Safe Mode to rule out plugins.

Please upload you diagnostics.zip (from Tools -> Diagnostics) while the problem is happening. You can also get them from the command line (click this link for details >>> diagnostics )

Have you set the server's name and localTLD to match the cert? Read the intro here https://docs.unraid.net/unraid-os/manual/security#securing-webgui-connections-ssl then scroll down to "Custom Certificates" If you still have questions please post the diagnostics.zip (from Tools -> Diagnostics)

Please post the diagnostics.zip (from Tools -> Diagnostics). It would be ideal if you could do this after making the problem happen, and then after making it go away so everything is captured in the logs. Thanks!

My Plex server only has 16GB RAM, with 4GB is allocated to CrashPlan and 4GB to an Unraid test VM... it basically started feeling too tight to let Plex take some of the remainder for transcoding. Not exactly a problem you have though : )

This might be what you are looking for: https://docs.unraid.net/connect/help#how-to-access-your-server-when-dns-is-down

The .local domain uses Multicast DNS ( https://en.wikipedia.org/wiki/Multicast_DNS ) so an actual DNS server is not required. It is the only domain that works that way though, all other domains require a DNS server. The easiest solution would probably be to use the DNS server that your domain registrar provides, assuming they let you point at internal IPs. Cloudflare can work too. Note that you may need to disable DNS Rebinding Protection on your router and/or DNS servers to let clients resolve local IPs for FQDNs. You may find this page of the docs helpful: https://docs.unraid.net/unraid-os/manual/security#securing-webgui-connections-ssl

And disabling IPv6 makes those messages go away? Would you mind sharing diagnostics that show that?

You are getting call traces related to macvlan, please see the known issues section of the 6.12.0 release notes: https://docs.unraid.net/unraid-os/release-notes/6.12.0#known-issues Also, if I'm reading your syslog correctly it looks like you have a Realtek RTL8168h/8111h NIC. You may benefit from these 3rd party drivers: https://forums.unraid.net/topic/141349-plugin-realtek-r8125-r8168-and-r8152-drivers/

Please upgrade to 6.12.3 and try again, it includes fixes for networking and Docker: https://forums.unraid.net/topic/142116-unraid-os-version-6123-available/ Be sure to read that announce post to prevent issues when shutting down the array in 6.12.2

RE: transcoding in RAM... Oh yeah, I ran like that for a while. Normally Docker containers are isolated from the system so the container can't hurt the host. If you override that by giving the container access to a system folder like /tmp, there is the chance that the container can cause problems for the host when something goes wrong. That is essentially what happened here, a problem with Plex filled up the system's /tmp folder and caused problems for the OS.

This fix is included in 6.12.3, be sure to read the announce post when upgrading:

This thread is perfect for quick questions or comments, but if you suspect there will be back and forth for your specific issue, please start a new topic. Be sure to include your diagnostics.zip.

My first question is does the system eventually recover? But this seems like a topic that will take a bit of back and forth, so I'd suggest creating your own thread and uploading diagnostics. It is very difficult to have a lot of back and forth in a release thread.

Plex is mentioned specifically in the release notes (which I know you read : ) ) so if you continue to have issues add --no-healthcheck as mentioned there If you have a thread discussing this, be sure to add new diagnostics after upgrading to 6.12.3. If you don't have a thread, please create one specific to this issue. It is very difficult to have a lot of back and forth in a release thread.

Yeah, there are special instructions in the 6.12.3 announce post to help folks get past that: https://forums.unraid.net/topic/142116-unraid-os-version-6123-available/ Glad you figured it out on your own, kind of impressed really : )

This thread was created 4 months ago for an older release of Unraid. I'd suggest upgrading to the recently released 6.12.3: https://forums.unraid.net/topic/142116-unraid-os-version-6123-available/ If you continue have issues that aren't covered in the "Known Issues" portion of the release notes then start a new thread and be sure to include your diagnostics

Thanks everyone for the help testing. These fixes, plus a few more related to networking, are now available in Unraid 6.12.3: We encourage everyone to upgrade

The 6.12.3 release includes a set of bug fixes for networking and Docker. All users are encouraged to upgrade. Please refer also to the 6.12.0 Announcement post. Upgrade steps for this release As always, prior to upgrading, create a backup of your USB flash device: "Main/Flash/Flash Device Settings" - click "Flash Backup". Update all of your plugins. This is critical for the NVIDIA and Realtek plugins in particular. If the system is currently running 6.12.0 - 6.12.2, we're going to suggest that you stop the array at this point. If it gets stuck on "Retry unmounting shares", open a web terminal and type: umount /var/lib/docker The array should now stop successfully (This issue is resolved with this release) Go to Tools -> Update OS. If the update doesn't show, click "Check for Updates" Wait for the update to download and install If you have any plugins that install 3rd party drivers (NVIDIA, Realtek, etc), wait for the notification that the new version of the driver has been downloaded. Reboot This thread is perfect for quick questions or comments, but if you suspect there will be back and forth for your specific issue, please start a new topic. Be sure to include your diagnostics.zip.

Sorry, In order to use Unraid Connect Remote Access you would have had to set it up before leaving your house: https://docs.unraid.net/connect/remote-access You mentioned having a myunraid.net url, but I'm guessing you just setup SSL for local access and didn't actually setup Remote Access?

Unraid Connect Remote Access is only able to give you access to the Unraid webgui, not to your Docker containers. If you need to access Docker containers or VMs or other items on your network, you'll want to setup WireGuard VPN:

Looking at the diagnostics, I am unclear what network card you have. It might be based on the RTL8125 chip or it might be RTL8226/RTL8221. Either way, it is definitely not the RTL8168 so it makes sense that installing the wrong driver would cause issues. If you can figure out which network card you have and install the driver appropriate for that card you may have more success. Or if your system is working fine then you may not need a different driver for your hardware at all. Keep in mind that plugins are provided free of charge by other community members because they want to be helpful. You may want to consider editing the language on your earlier posts.

If anyone is having issues with the array not stopping, there is a quick fix in https://forums.unraid.net/topic/141479-6122-array-stop-stuck-on-retry-unmounting-disk-shares/#comment-1283203 Unraid 6.12.3-rc3 has the fix built in, if you'd like to test it:
