We have a few Polycom phones in our region (many more in the future) and periodically they will display a message indicating that the Lync Sign In has failed. This happens with phones that are using a PIN login, a manual SIP login, and phones that are connected to a PC and receive their credentials from the Skype for Business client.
Most recently I happened to notice this happen while I was at my desk on a Polcyom VVX500 which is getting credentials from the connected computer (Better Together).

Each time it logged in successfully and automatically without me having to re-enter credentials.
Here are two example phones and versions we are currently using, but this issue has persisted through a few different software version updates:

Hi stuzzicadenti, i'm experiencing the same issue with our VVX 500 phones with pretty much the same setup as yourself.
Just wondering if you have had any success solving this issue?
