ssl-mode should default to a mode that tries to autodetect server support, with automatic fallback to disabled(PREFERRED, per https://dev.mysql.com/doc/refman/8.0/en/connection-options.html #option_general_ssl-mode), but I'm not sure if that works properly with the Aurora server.
Have you looked at https://aws.amazon.com/premiumsupport/knowledge- center/rds-error-2026-ssl-connection/? The error message you get doesn't quite match what is mentioned there or what MySQL would report if the problem was that the client tried to enforce ssl, but I did find https://github.com/microsoft/msphpsql/issues/1023 which also mentions it working in 19.10 but no longer in 20.04. Maybe something related to openssl 1.1.1f? ** Bug watch added: github.com/microsoft/msphpsql/issues #1023 https://github.com/microsoft/msphpsql/issues/1023 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1872541 Title: MySQL client fails to connect, seems to force SSL To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-release-notes/+bug/1872541/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
