Icinga2 masters accessing agents in different domains

Hi all,

we have an incinga2 master installed on RHEL 8 in one domain e.g. domain1.rz.
Now we have an agent1 in another domain e.g. domain2.com

agent1 could be registered to the master (key…) but does not perform any check.

Any idea?

Thanks for your help.
