Scope | FortiSIEM. |
Solution |
While trying to register the collector with the correct credentials, the collector shows the following error.
Upon checking further in AppSvr logs from Supervisor, the following error has been noticed:
tail -f /opt/glassfish/domains/domain1/logs/server.log
The error suggests that AppSvr is preventing collector registration due to the Trusted Hosts configuration applied from Admin -> Settings -> System -> Trusted Hosts.
As a Solution, collector IP can be added to Trusted Hosts, or existing IPs can be removed from Trusted Hosts. Try registering the collector again, and it should be registered successfully. |
