Re: ERROR 2013 (HY000): Lost connection to MySQL server at 'reading authorization packet', system error: 95

That tells us your current MySQL instance found the MariaDB audit plugin and loaded it.

To find where it came from, try something like ...

rpm -qa --last | tac

or pass such output through grep.

For how to disable it--ie to discover if it is the cause of your issue---see https://mydbops.wordpress.com/2020/08/30/integrating-mariadb-audit-plugin-in-mysql-5-7-2/
