All Tera2 PCoIP Zero Clients have an issue when connecting to Horizon View Connection Server (VCS) 8.x running in FIPS mode. Basically when trying to connect to a VCS in FIPS mode the connection never happens and the user gets a very generic error - "View Connection Server communication error".

 

This is due to a requirement for TLS 1.2 + EMS (Extended Master Secret) when connecting to a VCS running in FIPS mode. Tera2 PCoIP Zero Clients only support TLS 1.2 and TLS 1.3. At this time there are no plans to add support for TLS 1.2 + EMS.
