VVX310-Skype for Business sign in failed

[Anonymous]

Good afternoon

I am having a problem where i cannot login a Skype for Business account on a VVX310 i have setup for testing. i tried logon from the web page and get an error saying "Skype for Business Sign in Failed". The phone firmware was just upgraded from 5.5.3  to 5.7.2.1277.

Skype/Lync is on premise and version is Lync2013 servers.

Phone info:

Model: VVX310

UC Software version: 5.7.2.1277

Updater:5.9.2.1208

Base Profile: Skype for Business
Web Server: Enabled
Web Config Mode:HTTPS

I have attached the app logs from the phone.

Thank you

Hello @Kola,

welcome to the Polycom Community.

Has this ever worked or is this a new installation?

The community's Skype for Business FAQ contains this post here:

Resolution: Have a look => here <=

I can see some SSL errors in the logs so most likely its a Certificate issue.

Hi Steffen

It has always worked until i did the upgrade to to 5.7.2. i am not sure what to look for in the app logs that would point me to the issue.

So thanks to your troubleshooiting FAQ. I was able to find what the issue was.

The phone was looking for lyncdiscoverinternal.domain.com in DNS. there was no A record for lyncdiscoverinternal. i went ahead and created the record on my internal DNS server and the sign in completed successfully.
