Can't connect to Web UI

[Tealeaf]

I really need help with this if possible.

I can put the IP into the web browser and I can get a log in page, into which I complete the username & password. However the following page never loads (tried Chrome 64, Chrome 32, IE, Firefox and had same).
Page that never loads after login is at: http://xxx.xxx.xxx.xxx/servlet?p=status&q=load

Discovered next set of problems too:
The phone intermittently loses network. Then finds it again. Happened twice today.

Incoming sound is fine. My outgoing sound is very choppy. It's not a bandwidth issue (40Mbps upload speed), anyone got any suggestions?
