Error: Something Bad happened?

I'm having trouble configuring a desk phone and assigning an extension to a new user... 

I know the phone can get to the internet, and they are all on a dedicated VLAN, but the admin console shows the phone as unavailable, with error messages happening sporadically. It was able to connect and sync once, and never again from there. I am factory resetting the phone now.

As for the assignment of an extension I get a message that the request is malformed... tried on Edge, Safari, and on a Mac and Windows. Same issue.

Anyone know if there is a fix? Not much info to go off of based on the error message... Or is this on the GoTo side? It's kinda driving me nuts.
