I have created a micro Service application and added the APNS library of type "com.notnoop.apns" and version "1.0.0.Beta6".I have deployed this application on GCP on a kubernetes Cluster. The push Notifications were working fine. But sometimes I am getting the below Exception

This issue is being Reproduced many times now a days and If I am Restarting the Service in google Cloud, Then the Push Notifications are Working Fine but again after sometime I am facing the same issue. I have even checked with the validity of the Certificate and its not Expired yet.
