Cause:

  • When MSA not able check the MMS status this issue would occure.

  • Check if there is any firewall is trying to block the MMS server (jsdr-mms.azurewebsites.net/40.112.243.46) via port 443.

Resolution:

  • Allow the port 443 for MMS server and verify the connectivity from MSA using curl command (curl -v https://jsdr-mms.azurewebsites.net:443

  • If it is connected wait for some time and see if the warning goes away automatically.

  • If the warning stays then restart the vme2 service on MSA will resolve it #service vme2 restart
