Description of problem:
RHEL8 has a trouble with Bluejeans.
Once someone connects to a bluejeans session beyond himself he just gets an
endless spinners saying 'waiting on video'.
After some investigation it looks like the WebRTC on RHEL8 does not receive any data so there's no content to show - but not sure why that happens.
It seems that webrtc connection needs TLS 1.1 which is disabled by default in RHEL8. The workaround for this is:
sudo update-crypto-policies --set LEGACY
Switching to nss component as long as we can't do much about in from the Firefox point of view.
the call of ssl3_NegotiateVersion fails with SSL_ERROR_UNSUPPORTED_VERSION
can be debugged with:
$ export MOZ_LOG="mtransport:5"
I would say this is by-design and there is a workaround. BlueJeans should not require TLS-1.1.
