Hello James,
there should not be any other software released at present other then 5.9.5.2831 for the C60.
We are due to release UC Software 5.9.5 Rev AB tomorrow or Monday latest.
If there still is an issue:
May 11, 2018 Question: Why do I get a "Failed to fetch available software from the Poly hosted server" error message or able to download list but unable to upgrade/downgrade?
Resolution: Please ensure your firewall allows outbound network traffic as shown => here <=
Best regards
Steffen Baier
