SSL connection fails

[rmcd1024]

I'm using 1.4.8+2snapshot.g0adeaf9 on Ubuntu 20.04 and it was working well until August 1. (The date makes me suspect a server-side change that is causing the failure.) Now I get an SSL error when I attempt to connect:

Here is a similar problem #96. You could try https://github.com/dlenski/gp-saml-gui to see if it works for you.

I couldn't get gp-saml-gui to work. I finally fixed the issue by upgrading from Ubuntu 20.04 to 22.04, which upgraded openconnect from 8.10 to 8.20. (I assume the openconnect upgrade is what worked.)
