EWS Managed API code execution freezes on syncFolderItems

[kulesshhh]

We currently migrated our existing .net framework code to .net core to read emails from multiple email accounts every few minutes.
It was working fine on our .Net framework version but it stops working many times since its deployment on AWS Kubernetes environment using .Net Core. It only starts working again when we restart the application/pod

We tried to diagnose the issue by adding logs and found that code execution completely hangs on the line :

I am using the library Microsoft.Exchange.Webservices.NetStandard.dll (2.2.0)
.Net Core v 3.1

Please help!

Thanks in Advance..
