Thanks for the openSSL config example! I set up a Bionic and a Focal VM,
both with client and server, to test this.
Without this config, the connection does not work in any direction, i.e.
the Bionic client won't connect to the Focal server (with a chat message
saying "remote host closed connectio

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
Sure. But if this is controllable from a configuration file, then it
might be possible to come up with a temporary work around until the
server you want to connect to is upgraded. With any luck, the
configuration can be changed in such a way that only Mumble is affected.

This could work as a temporary fix. However, "re-enable old crypto
protocols that should not be used unless absolutely unavoidable since
RFC 7525 five years ago" must not be the final resolution for this bug,
since it's exactly what Focal wants to avoid. From a crypto standpoint,
while TLS1.0 is no
This is likely caused by bug 1856428, which indicates that support for
the older TLS versions can be enabled in a configuration file.

I encountered this today too. This seems to be an OpenSSL problem,
given that "openssl s_client" refuses to connect to the server, where it
succeeds with older releases. Presumably the server only supports
ciphers or TLS versions the new OpenSSL rejects.
