Alright, so a recently I got a message from my Uptime Monitor that my Discourse Forum went down. I checked what was going on. It was offline. Though the server it was running on was online. I rebuilt the app to start it again.  
Then I got this error:

The only error messages I found, were following:

I don‘t have anything else running under that port though.

Can anyone help me? I do not know what I should do.

Thanks in advance.
