Connection security

Ehenomenon

  • I can connect from Azure Cloud Shell.
  • I can connect from local DBeaver client (Community Edition 21.2.3).

CodePudding user response:

It looks like there is a problem with the latest MySQL 8.0.27 release. I've encountered the same issues you describe when trying to connect using the command line from different MacOS and Linux machines.

There 's also a bug reported here: https://bugs.mysql.com/bug.php?id=105288 I suggest you add your findings to it as well.

I tried a bunch of different things before simply rolling back to 8.0.26, which still works fine for me.
