After configuring the Messaging Gateway (SMG) Control Center for policy sharing as described in About configuring a Control Center cluster for policy sharing policy sharing does not operate as expected and the following warnings appear in the BrightmailLog.log:
Jul 26 2022 22:39:39 [ActiveMQ Task-1] [FailoverTransport] WARN - Failed to connect to [ssl://127.0.0.1:41616] after: 20 attempt(s) with java.security.cert.CertificateException: No subject alternative names matching IP address 127.0.0.1 found, continuing to retry.
Release : 10.7.5
Component : Management Console
The SMG Control Center is configured to do remote syslog logging in Administration > Logs > Remote which is causing the web application to attempt to connect to the policy sharing message broker on the wrong interface.
This is a known defect and will be addressed in a future release.
Disable remote syslog for the SMG Control Center:
Once this change has been saved you will need re-enable Policy Sharing in Administration > Control Center > Policy Sharing.
