GUI isn't working, SSH isn't working

[Queless]

Hello. I deracked/reracked my server and changed IP addresses. For some reason after reconfiguring the server for the new IP I'm no longer able to use the browser GUI or am I able to SSH in. Using the command "service pve-cluster restart" I was able to fix it and use the web GUI but was still unable to SSH(obviously). For some reason after a restart(or possibly a crash) I'm not able to access the GUI again. I'm able to ping google. I'm using proxmox 4.

Can anyone help me figure out what dumb thing I did? Thank you

Update: service pve-cluster restart no longer fixes the web interface. No other changes have been made except to virtual machines. I'm totally lost here.

Is SSHd running (ps waux | grep ssh)? What happens when you run "telnet localhost 22"?

Is your (old) IP hardcoded in /etc/ssh/sshd_config? If yes, change it and run "service ssh restart".

What are the nameservers in /etc/resolv.conf? If they are from your old ISP you may need to change them. You can try with 8.8.8.8 and 8.8.4.4 (Google's public resolvers).

Only changed the IP, not the hostname also?

Connected to localhost.localdomain.

No, and I also changed it after changing IPs (It was 0.0.0.0 before)

I'm able to ping google so DNS is working, but regardless it's set to google's DNS already.

The hostname where?

Thank you much for the reply

Connected to localhost.localdomain.

That's all? If that's it, it really looks like a DNS issue, but strange that DNS seems to work fine for resolving Google (does it resolve unknown domains also fast?) You should get something like:

root@node02:~# telnet localhost 22
Trying 127.0.0.1...
Connected to localhost.localdomain.
Escape character is '^]'.
SSH-2.0-OpenSSH_6.7p1 Debian-5+deb8u2

If you keep it open for a while, is the protocol/version info displayed then?

Can you post your /etc/ssh/sshd_config?

The hostname where?

Your hostfile and /etc/hostname. But if you didn't change it's OK.

What does "netstat -l | grep ssh" and "netstat -l | grep 8006" show?
