Hello,
I can’t see my discourse page at the usual page (ceprovamos.tk), I can see only the default Apache2 Ubuntu Default Page.
I had forgotten to pay the cloud service and they stopped my server. Then I payed and restarted the server. Now my discourse disappeared and I can see only this default page, advising me to replace the file /var/www/html/index.html, but I don’t know how.
Obviously before this inconvenient Discourse was working perfectly.
If I do cd /var/discourse/launcher start app
the answer is: Error response from daemon: Cannot start container app: failed to create endpoint app on network bridge: Error starting userland proxy: listen tcp 0.0.0.0:80: bind: address already in use Error: failed to start containers: [app]
As you noticed I have a quite poor knowledge of website administration…
And what should I do? I don’t have idea…! To install discourse I’ve just followed the official guide accurately. I never edited any settings of Apache or anything else
Solved.
I simply removed index.html file and index.nginx-debian.html file in /var/www/html, and I removed apache2 and nginx. Now my Discourse forum runs again.
Probably I installed apache2 and nginx months ago trying to host more discourse forums on one server. And when my hosting service stopped my server something was reset as you said…
