This article is one I thought I had written ages ago, but didn’t. So, here it is.
Got a Surface hub that wont sign in to Skype and you cant figure out why?
Well first make sure you can sign in with a normal Skype client 99% of Surface Hub issues are because of DNS or Certificates
Keep in mind a Surface Hub signs in like the Windows Modern Skype client (remember that thing) so there are a few extra requirements
You can also test the account using the old school offline Lync Connectivity Analyzer tool.

If your still stuck. You can then collect logs from the Surface Hub itself, you will need to plug a USB stick into the right side usb port.
The ports underneath will not work
On the Surface Hub navigate to Settings > Update and Security > Recovery and click on Collect Logs
This will take a while as it collects logs and system information but eventually it will spit out a file similar to Logs_HostName_2019_01_26-04-47-58
Once you have the ZIP file you can extract it and then find logs in %logfilefolder%\skype\PPISkype-Lync-0.Lynclog
Open this lynclog file in Snooper as you would a standard uccapilog file
Start reading.(if you need a hand with snooper, there is a great guide over here)
Oh I’ve had one scenario where the unit didn’t log any sip messages or DNS resolution in the UCCAPI logs. Turns out it was a routing issue to the Reverse Proxy.
Hope this helps.
