Thank you for posting a Diag file.

90% of the time this is ECCE Ram Memory correction. If it is the cehck event was a warrnign that ram was corrected.

Unriad the Host OS it self sits in ram. On intel you can run mcelog if no output it was ecce ram memory correction if output then thats the issues.

Its best when you hit a MCE to reboot unraid and at the grub boot menu run the memtest applciation to rule out faulty hardware.

If AMD mcelog applciaiton doesn't work for you, your better off installing the CA Plugin live memory test and also to reboot unraid and at the grub boot menu run the memtest application to rule out faulty hardware.

I ran the memtest for 4 passes and everything was great, no errors at all. However, now I have a new problem, I increased my Docker size a while back (I'm not sure why, I was tinkering around). I deleted the image to go back to 20GB, and then I was going to add back my containers from the templates. Well, the templates wouldn't load, so I figured I'd load them from the community apps tab and configure as needed. Then I couldn't get community apps to load, so I did the updates needed and it still wouldn't load. I deleted the community apps plugin and tried several times to no avail. It keeps throwing the error:

Download of appfeed failed.

Community Applications requires your server to have internet access. The most common cause of this failure is a failure to resolve DNS addresses. You can try and reset your modem and router to fix this issue, or set static DNS addresses (Settings - Network Settings) of 208.67.222.222 and 208.67.220.220 and try again.

Alternatively, there is also a chance that the server handling the application feed is temporarily down.

Last JSON error Recorded: Syntax error

I have tried:

• changing my DNS settings on unraid to the ones suggested in the error

• changing them to Google's DNS

• restarting my router (I have the Xfinity xFi - I'm already looking into changing it, just trying to find the best combo)

• resetting my router

• running Fix Common Problems - it shows this as the only comment:

  • Could not perform unknown plugins installed checks | The download of the application feed failed.

• only apps.unraid.net fails DNS resolution globally

I'm not sure what else to do. I'm really hitting a wall here.
