One of my forum goes offline. I checked on sever but everything is working fine on server side. Another forum is working fine but one goes offline. Is anyone here facing this issue. It will be great if anyone here will share how and when forum comes back online. Thanks

Sorry, I copied and pasted it with an extra parameter, can you run it once more, using this (note: the missing -t argument) sudo lsof -i tcp:80 -s tcp:listen

[image] cpradio: sudo lsof -i tcp:80 -s tcp:listen [3]

Perfect, so you have apache2 installed which is taking over port 80. Are you running other sites on this server (other than Discourse)?

Nope, only this one. I am using Digital Ocean. I have one more Discourse but that is on another server and that is working fine. Only this one is affecting

okay, try running sudo apt-get remove apache2 If that doesn’t solve the issue, run dpkg -l | grep apache2 and remove each remaining component

[image] cpradio: dpkg -l | grep apache2 I tried both but problem still exists

Run the sudo lsof -i tcp:80 -s tcp:listen command again, is anything listening on port 80 anymore? From what I can tell, that is simply implying that apache2-bin apache2-data apache2-utils can be manually removed as well. sudo apt-get remove apache2-bin apache2-data apache2-utils The rc in front of apache2 means it was removed, but still has configuration files sitting on the system.

now,. nothing happens this time.. It is not listening on port 80 anymore

If discourse was already installed, a reboot should be sufficient for starting it back up, or you can run cd /var/discourse ./launcher rebuild app
