Snapshot failed due to maverick.ssh.SshException. Your subscription has expired

Hi Experts,

We have deployed NA 2021.05 which was working perfectly fine with respect to taking snapshot.

From couple of days we have observed that snapshots are failing and when checked the error in the session log

"com.maverick.ssh.SshException. Your subscription has expired, visit www.sshtools.com to purchase a subscription

Any solution?

Thanks and Regards

Vinay
