Description

The FreeRDP lib, which gucamole depends on for RDP connections,  fails to perform a proper handshake with a windows 2019 server when both TLS1.2 and TLS1.3 are enabled. A fix has been put in the FreeRDP lib (see Github link in External issue URL) to enforce TLSv1.2 during connection handshake. 

Gucamole server project needs to target the version of FreeRDP that has this fix.
