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

What is occupying the port 80 on your server?

Run this command, to identify what is taking up port 80 (and then provide us the output)
`sudo lsof -t -i tcp:80 -s tcp:listen`

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`

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

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.

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

Anything taking up port 80 again? Are you sure it is the same error?
