Comment 17 for bug 1872541

The problem with using ssl is that you are using a client (openssl 1.1.1f-based) that will not speak anything older than TLS 1.2, trying to connect to a server that can only speak TLS 1.1.

From 1.1.1f-1ubuntu1 changelog entry (https://launchpad.net/ubuntu/+source/openssl/+changelog):
    - Set OPENSSL_TLS_SECURITY_LEVEL=2 as compiled-in minimum security
      level. Change meaning of SECURITY_LEVEL=2 to prohibit TLS versions
      below 1.2 and update documentation. Previous default of 1, can be set
      by calling SSL_CTX_set_security_level(), SSL_set_security_level() or
      using ':@SECLEVEL=1' CipherString value in openssl.cfg.
