Monitoring backend 'icinga' is not running

Since the 2 master’s weren’t sync after i used local database for each. I now have added a seperate database node and changed the ido config with database ip and enable_ha = true.
now the monitoring shows error as Monitoring backend ‘icinga’ is not running.
I would like to know what is the problem with this
I can access the database from both master’s by running mysql -h -u icinga2 -p succesfully.
Can someone help please
