I'm playing with a multi server setup that has Debian 8 master on WAN and Debian 9 slaves on LAN. Everything works nicely except the "System State" updates. For some reason they get stuck in the queue. Code: datalog_status_u_server: 24 datalog_status_i_server_ip: 1 datalog_status_u_server_ip: 1 All servers have the save versions of ISPconfig.
This normally means that the slaves are not allowed tologin to mysql on the master. you can check that in debug mode.
