Hi icinga2 community!
I had two masters. Master1 was config master. Both master fully setup with database but no ha.
My master1 failed and I had to turn off master1. Copied the conf files to the master2.
Everything works fine with the current agents, but now I want to add a new agent and I see the message “certificate validation failed: code 18: self signed certificate”
I ran icinga2 wizard manually and followed the step accordingly.
What could be my problem no now clients can connect to master2 ?
Master2 version: r2.11.2-1
New Agent: version: r2.11.3-1)
Could the ‘newer’ agent be a problem?
*EDIT: found (probably not) my problem?. I tried to make the icinga2 wizard installation easier by providing and showing the ticket using curl “generate ticket” before I start the icinga2 wizard but that logically! still needs local signing.
