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.

How was this installed?
What else is on the machine if anything?

It was installed a while ago following the install guide. It just randomly went offline.
I run a Minecraft Server on the Server too. Though, it does not use Redis and it uses port 19132 so that should not be a problem. It has always worked with it. What I have noticed though, that if I go to the domain to my forum I get a page from nginx saying it works.

If you `docker ps` what do you see? What’s the output of `docker info`?
Which plugins do you have installed?

Sorry for the late response:
I only had one plugin installed, the Check Mark thing for support.

And if you `netstat -tulpn | grep 6379` ?

Command not found.
Do I need to run it in the discourse folder?

Is the server running ubuntu?
If so `sudo apt-get install net-tools`
The path you run it from isn’t important.

It‘s running debian, which is basically ubuntu… Yeah.
I‘ll install that then I will run the command.
