Nothing is working. Domains, subdomains.

Hello all,

I've noticed that I couldn't access my website so I thought i'd access the CP. But I can't access it from the domain. NONE of my domains are working. The error I get is "ERR_CONNECTION_TIMED_OUT". I can access the CP on the internal IP address ie "192.168.1.150".

The panel shows around 2.5GB/16GB, 2% CPU usage

CWP7 is running on a Dell PE R410

I've tried a reboot but nothing. This error is new to me. If I ping my domain it comes up with the IP address, the ports are open etc, nothing has been changed.

EDIT

I've just done a website checker and it could access it.
I went onto my phone and used my data and I could access it. So it's a internal error. Maybe router?

Fixed it, wasn't anything to do with the server. I just rebooted my internet and that seems to have fixed it
