Forti-Analyzer : SSL Error with D & E Series Fortigate

[Owen_Air]

Hi There, 

I have a Forti-Analyzer hosted in azure running V7.4.1 most the D series and some E series firewalls are not able to connect to the FAZ and there's an SSL error generated on test and in the system logs.

I do have other models which don't have the issue, I have 58 devices in total (60E, 61F, 81F, 60F, VM64 - Azure) 

The firewalls which are having issues are on the following versions -

60D | 6.0.17 Build0528 (GA)

80E | 6.0.16 Build0505 (GA)

90D | 6.0.16 Build0505 (GA)

The error message generated in the system logs of the firewalls are as follows. 

Log Description FortiAnalyzer connection failed

Action connect
Status failure
Reason ssl_connect() failed: 1

Event
Message Failed to connect FortiAnalyzer "IP Removed"

Log event original timestamp 1697620251
