I found in the past that what works is one of 2 below things (not always recommended, but they do work)
1- create a dummy duplicate cp host ( NOT regular host, but the one where it lets you choose it as logging server) and then once you save that, go to logs under firewall and add that new object as logging server (just give it same IP as actual mgmt object). Install database, push policy. If logging works, then leave it like that for 24 hours, then delete dummy object and revert back to old config.
2- edit $FWDIR/conf/masters file on affected gateway and change name in all 3 fileds to actual mgmt IP address reflected in dashboard object. Also, apply below sk:

Alternatively, please follow what @Tal_Paz-Fridman mentioned, those are all valid points.
Please update us on results.
