Debug/Workaround for 8894713: Refreshing access token call gets stuck causing delay in Mail Fetching Schedule

Issue:

      Mail fetching schedule doesn't fetch new mails intermittently. On analysing logs, we could infer a http call to Token url to refresh the access token doesn't respond and the schedule thread is made to wait indefinitely for the response. This leads to the issue.

Fix:

      A debug/workaround has been prepared where connection and readtime are set as 30s for the HTTP Request sent to Token url. On timeout, error will be thrown which should eventually reschedule the mail fetching schedule. This also prints debug traces in the logs.
