MySQL Workbench 8.0.11rc SSL connection error: error:00000001:lib(0):func(0):reason(1)

Good Morning Everyone!

I'm trying to connect to MySQL server 8.0.11 using MySQL Workbench 8.0.11rc but I get the obscure error message:

SSL connection error:
error:00000001:lib(0):func(0):reason(1)

MySQL server is setup to require secure transport using caching_sha2_password. In my create user statement I'm using REQUIRE ISSUER '/CN=CACOMMONNAME' AND SUBJECT '/C=COUNTRY/ST=STATE/L=LOCALITY/O=ORGANIZATION/OU=ORGANIZATIONALUNIT/CN=CLIENTCERTCOMMONNAME

The connection works if I downgrade the user to REQUIRE SSL on the server. I then delete the client certificate paths from MySQL workbench and select REQUIRE or REQUIRE AND VERIFY CA from the dropdown box. Test connection and voila! I get a valid response.

However, this isn't good enough. I'd rather have the additional security checks but I seem to be at a stand still. What do I do to get this to work using the client certs in Workbench and REQUIRE ISSUER/SUBJECT on the server? What does this message mean? There are no error messages or hints in the log files on the client or server.

The only thing I see in the log files that could indicate a possible problem are the lines:
10:09:19 [WRN][ grt]: C:\Program Files\MySQL\MySQL Workbench 8.0 CE\modules/data/mysql_rdbms_info.xml:1391: link 'om.mysql.rdbms.mysql.driver.native_sshtun' <object > key=owner could not be resolved

What does 'key=owner could not be resolved' mean?
