I have more recently run into an very odd issue.

 

Unraid's web gui will become unresponsive, however if I wait a minute or two, it will load. I get about 30seconds to 1min of use, then times out. 

Docker's won't update (timeout) sometimes - if I can get it to happen quickly.

Have CrushFTP - timeouts trying to connect sometimes, again if it's in that working period it's okay.

 

Attached diag's 

 

I don't know if I need to rebuild and start everything from scratch. 

But it's a real pain right now.

Check the ethernet cabling or try another port on the switch.
