We are facing the issue with some customers where suddenly Qmc and Hub are not opening whith error "connection refused" although all services are started.
We observed in System_Repository log error "There was an error contacting the license service. Keep retrying..."
and in LIcenses log errors like
..."failed to create message queue client: pq: no entry in pg_hba.conf for host \"xywz::xywz:\", user \"qliksenserepository\", database \"QSMQ\", SSL not enabled","timestamp":"" and
"failed to create service: pq: nessuna voce in pg_hba.conf for host \"xywz::xywz:\", user \"qliksenserepository\", database \"QSMQ\", SSL not enabled","timestamp":""}
in event viewer also could be find similar PostgreSQL warnings regarding pg_hba file.
the way we resolved the issue was to enable full IPv4 and IPv6 address range to all databases adding lines
host all all ::/0 md5
host all all 0.0.0.0/0 md5
and restarting services.
Currently we observed this issue only for configuration with version 12.5 of PostgreSQL and server were running fine before suddenly this issue was thrown out.
Is someone else facing this issue ? And which was the solution applied?

Nicola Papapicco
