Description:

The command below hangs forever trying to connect to the Azure MySQL Db
$ /mysql -h <host> -u <user> <db>
The same goes for MySQL C API (mysql_real_connect() blocks forever)

Downgrading mysql-client v.8.0.26 made the problem disappear.

Extra info

$ mysql -V
mysql  Ver 8.0.27-0ubuntu0.20.04.1 for Linux on x86_64 ((Ubuntu))
$ lsb_release -a

Connect to the remote Azure Db (with SSL enabled)
$ /mysql -h <host> -u <user> <db>
