From the MSA, navigate to /var/lib/vme2/logs/ > jss.log

and review the file.
If there is a communication between the MSA and MMS servers an MMS connection timeout error may be reported:

When MSA not able check the MMS status this issue would occure.
Check if
...
a firewall is
...
blocking the MMS server (jsdr-mms.azurewebsites.net/40.112.243.46)
...
on port 443.
Resolution
...
Allow the Open port 443 for on the MMS server and verify the connectivity to it from the MSA using the curl command (:
curl -v https://jsdr-mms.azurewebsites.net:443If it is connected wait for some time and the connection appears valid, wait a period of time to see if the warning goes away automatically.
If the warning stays then persists, restart the vme2 service on the MSA will resolve it #service vme2 restartusing the command:
#service vme2 restartThe PostgreSQL and Tomcat8 services used by JetStream DR software will be stopped and then restarted.
The PostgreSQL service is the MSA DB service and the Tomcat8service is a webserver service.
Verify that status of the MSA services using the command:
#service vme2 status. PostgreSQL and Tomcat8 services should both appear running.
