Problem:
The JetDR UI might indicate a warning as “Subscription status unknown. Please check the management server’s external connectivity”
If you navigate to jetDR > configurations the subscription ID will report a yellow tag (if we hover the mouse pointer it will report Unknown as below)
Troubleshooting:
Validate the connection from MSA to the MMS server (40.112.243.46). If it fails, it may report as bellow (in this case subscription issue is expected)
[root@fs087-msa ~]# curl -v https://40.112.243.46:443
About to connect() to 40.112.243.46 port 443 (#0)Trying 40.112.243.46... Connection refusedcouldn't connect to hostClosing connection #0curl: (7) couldn't connect to host
From MSA navigate to /var/lib/vme2/logs/ → jss.log will report MMS connections timeout (as below), if there is a communication between MSA and MMS server.
2023-12-08 14:44:18,912 ERROR [Thread-8] (ReplicationSiteHelper.java:490) MMS status check failed.at com.jetstream.jss.task.systemtask.MmsCommunicationTask.updateStatus(MmsCommunicationTask.java:152)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
Failure to address this issue and if the MSA is unable to validate the subscription ID, it could result in the suspension of VM protection. There is a grace period of 14 days before suspension occurs.
