Hi, I use ubuntu 20.0.4 and have been running the server a while with support for other versions of php and worked 100% until the last update to Linux. Then my control panel stopped working . and although my sites runs fine and they can access mysqli without a problem. when i run php -q update .php or ispconfig_update.sh --force I get the following errror Operating System: Ubuntu 20.04.5 LTS (Focal Fossa) This application will update ISPConfig 3 on your server. Shall the script create a ISPConfig backup in /var/backup/ now? (yes,no) [yes]: Creating backup of "/usr/local/ispconfig" directory... Creating backup of "/etc" directory... Creating backup of "/root/.acme.sh" directory... Creating backup of "/etc/letsencrypt" directory... mysqldump: Error 2013: Lost connection to MySQL server during query when dumping table `monitor_data` at row: 16 PHP Warning: mysqli_connect(): (HY000/2002): Connection refused in /tmp/update_runner.sh.eVhxexR4RN/install/lib/mysql.lib.php on line 112 PHP Warning: mysqli_query() expects parameter 1 to be mysqli, bool given in /tmp/update_runner.sh.eVhxexR4RN/install/lib/mysql.lib.php on line 113 Checking ISPConfig database .. mysqlcheck: Got error: 2002: Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (111) when trying to connect OK ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (111) Unable to call mysql command line with credentials from mysql_clientdb.conf I can however connect to my IspConfig_db by using mysql -h 127.0.0.1 -p . any Idee what I can do to fix this problem?
Start with this to rule out the usual suspects and get context: https://forum.howtoforge.com/threads/please-read-before-posting.58408/ That Error 2013: Lost connection to MySQL server during query seems strange, what kind of update was that last update to linux? Any errors during it?
As @Taleman mentioned, you have a problem with your MySQL/MariaDB server. You tested a TCP connect over the network, but the error tells you that the connections over the socket fail. The command to test connections over the socket is: mysql -u root -p and you must use the password from /usr/local/ispconfig/server/lib/mysql_clientdb.conf
Hi, I am able to connect to mysql -u root -p and the password in /usr/local/ispconfig/server/lib/mysql_clientdb.conf are correct. All my site is running 100% connecting to mysql this leads me to believe that the problem is somewhere in the config. What is strange we have been updating the server and using the server for the past year with no problems and now after the ubuntu updates the control panel stopped working

Check the root user record in MariaDB e.g. by using phpmyadmin, maybe the Ubuntu update modified/extended it in a way to limit certain access ways to use it.
