pmm-client qan module binds to 127.0.0.1 whereas all others bind to proper address

Okay, then I have an issue with the QAN-API then… I get the following message when I use the Query Module

QAN API error: “MySQL Query Analytics configuration not found”.
Check the /var/log/qan-api.log file in docker container for more information.

What port/protocal (tcp or udp) does the client talk to the server on?
