Unable to get the delta token due to SocketTimeOutExcepiton : read timed out

Question

Hi Team,

I'm trying to acquire delta token for a batch of users one by one using the delta query in Graph Api.
Some of the users are able to get the latest delta token but other are failing.
Found out that the delta query is being failed due to SocketTimeOutException : read timed out.

please find the full stacktrace below
