My forum is suddenly not connecting since this morning. After a ping query, my domain is still active. What exactly is causing my forum not to be connected for use? Updated November 16, 2023 The issue has been resolved. after several checks, the cause of the forum not being linked was found and resolved successfully. The problem we encountered this time is that port 587 is occupied and the container cannot start. Temporary solution: 1, use the command to view the process occupying port 587: netstat -tunlp | grep 587 2, use the command to kill the occupied port number process: kill -9 xxx 3. Restart the docker container: cd /var/discourse docker restart app

This sounds like a misconfiguration. Did you make any changes recently? This might help: https://support.cpanel.net/hc/en-us/articles/360047373534-Why-does-my-website-show-the-default-cPanel-page-

This is a Discourse forum? And you’ve somehow installed it behind cPanel? Is the docker container running? What do you get from docker ps and docker inspect app If this is a standard install, then someone changed the DNS for your site. Another thing that I’ve had happen with things like cPanel, is I tried to disable cPanel and did a standard install, but then every now and then some process would run and restart the cPanel-like thing, so I’d have to figure out how to stop Apache and restart the docker container.

[529a45b2a16029f89bb38363aa8f024] Hello. Confirmed to be discorse forum. Confirmation now is that there just doesn’t seem to be a dns setting. Was the dns removed? Or was there no dns setting from the beginning?

Now the server provider reply is " We tried to log into your VPS and viewed that there is no website data on this host, please contact your site builder to confirm if there has been any operation to remove the site or if Wangzhan is stored on another server." But my friend never did anything more after finishing the installation for me. We also don’t make changes to systems we are unfamiliar with as long as they are working properly. It was strange to test today and find no dns. What should I do to set the dns? Is the reason I can’t connect to the site this time because the dns isn’t set?

You’ll need to ask your friend what they did. It’s impossible to tell how they installed our what the issue might be.

That would depend on who provides DNS for your domain. Different service providers have their own way of doing it. There’s nothing unusual about DNS for Discourse. You just need to point the hostname you want to use to the server IP address you’ve installed Discourse on.

[mmexport1699011645550] [mmexport1699011643896] [mmexport1699011633751] Thanks for the reply. I’ve actually been running my forum safely for two months. Just yesterday it suddenly failed to link. Then after checking, I realized that there was no DNS information. This is very strange.

I strongly suggest you take a database backup and copy it somewhere safe - copy it to a different machine, or download it to your PC.
