Public bug reported: The update from 5.7.27 to 5.7.28 definitely caused some SSL issues for one of our production applications. I have an older Python app that uses SQLAlechemy to connect to MySQL using https://github.com/farcepest/MySQLdb1, and the latest update caused tons of _SSL connection error: error:00000001:lib(0):func(0):reason(1)_ errors in my logs, and prevented my application from connecting to the database, eventually causing the host to be blocked because it hit the max_connect_error limit. The same error also occurred when attempting to use mysql from the command line.
Manually reverting back to all 5.7.27-0ubuntu0.16.04.1 versions resolved the issue.
