[SOLVED] Fresh install can't access GUI

[boundingtire]

I installed v8.2 on a Dell PowerEdge R630 and can't figure out why I can't access the GUI.
https ://192.168.12.200:8006 gives me the cert warning. I accept the cert, and the connection fails.
I changed the IP to .201 and have the same issue.

I've tried FireFox and Chrome on two different computers. Feels similar to the issue I'm having SSH to it.

I know it isn't an issue with the connection between my computer and the server because I can access the server's iDRAC interface (h ttps ://192.168.12.229) on the server and run commands through the Virtual Console. I can access other devices by https on the network. When I had VMWare ESXi installed on the server I had no issues accessing https.

Thanks in advance for any feedback...

When I try to SSH to the proxmox server it seems to hang waiting for the proxmox server to respond for several minutes before the broken pipe error comes up.

Found answer here:

/etc/network/interfaces was misconfigured
I had address set to 192.168.12.201/32 instead of 192.168.12.201/24
