I wonder if the underlying cause of the problem is that Bionic's Mumble is compiled against Qt 4, which predates the newer TLS versions. I would have thought it'd get new versions automatically through new OpenSSL releases, but perhaps there is some incompatibility in there.
If that's the case, I wonder if Bionic's Mumble client can successfully connect to Focal's Mumble server?
I detailed the configuration file workaround here:
