DO you have "SslMode=None;" on the mysql connector string fsassets is using?

 From the looks of it, FSAssetService is trying to connect to the upgraded host using TLSv1 and the host is denying the connection because TLSv1 is deprecated and completely disabled in Ubuntu 20.04. Given that your stack trace references OpenSSL and not BoringSSL, I can assume you are using a version of Mono for FSAssets that is older than Mono 4.8.0 and does NOT include TLS 1.2 support. You can downgrade TLS security on the 20.04 host, but I’m not going to tell you how to do that because you should be using TLS 1.2. If you upgrade mono to newer than 4.8.0 you will gain TLS 1.2 support. (You should do this.)

Any suggestions on what do do about this?

If you love math and wish an equation would never end, try out Taylor Series Expansion! (stolen from XKCD)
