Server is running but webUI and SSH are not accessible

[djuniah]

My server seems to have gotten itself into an odd state.  All of my network shares are working and running at full speed, all of my services running in docker containers are also completely functional.  The webUI and SSH however are not working correctly.  The WebUI just doesn't load and when I SSH I get a login prompt that does function, but once i enter my password, it shows the "last login was X" messages and then never shows a prompt.  The display on the monitor doesn't show any errors and I can't seem to enter anything there with the keyboard.  I tried just tapping the power button and it did say that it was sending processes the kill command, but that was over an hour ago and all of my services are still accessible/running.  At this point i'm not sure what other options I have besides a hard kill and I really don't want to do that.  Does anyone have any other suggestions that I can try?

 

EDIT:  Just wanted to note that this isn't related to some config issue with another docker container trying to take port 80.  Nothing has changed in the past 48+ hours and this just happened out of nowhere.  Doesn't seem performance related as my other containers seem to be running fine (although i don't know for sure since i can't get to the webUI or terminal to run htop/top)

 

EDIT2: If i leave the webUI loading, after a very long time, nginx eventually returns a 500 error.

Please post the diagnostics.

Right but i can't get to the webUI, SSH, or the terminal at the moment.  Is there some other way that I could do that?

You can connect a keyboard/monitor to the server.

Sorry, just realized that I never followed up to this.  In my original post i mentioned that "The display on the monitor doesn't show any errors and I can't seem to enter anything there with the keyboard."  So doing it directly at the machine was no help.  I ended up just crossing my fingers and hard rebooting the machine as I couldn't see any other way to get at it.
