Good morning,
I migrated Centreon from Centos 7 to Debian 11, everything was going well, but since yesterday, my central server has been in this state. see image above.
I did everything: restarted all the services that were active: centreon centengine, gorgoned, cbc, I even restarted the machine. I disabled IPv6. everything but it remained in this state.
you have an idea ?
