For the records, this is not related to acs. Setting the correct Mysql version in ProxySQL helps: set mysql-server_version='8.0.40-31.1';

Without proxysql everything is working fine. ProxySQL configuration also seems to be fine, I can connect via mysql cli without problems. But if the ACS Management starts and tries to connect to the database, I am getting a proxysql error: 2025-05-15 15:08:15 MySQL_Session.cpp:4608:handler_minus1_LogErrorDuringQuery(): [WARNING] Error during query on (1,10.xx.x.15,3306,177354): 1193, Unknown system variable 'query_cache_size' Does anyone have a hint what acs is doing here? Query_cache_size was removed in 8.0 Thanks! Juergen
