Hello @fanemama, the first error message indicate that the background scheduled task that is responsible for renewing the auth token at regular interval is failing to do so at certain point. If this is happening often then it possibly indicating an unstable network between application running consumer and AD endpoint or broker. I wonder if there is a restricted network or proxy or some kind of firewall rules that result in dropping the connection often.

Hi  @anuchandy ,
To give you more contexts, All our application developped in .Net or Python doesn't have this issue. We only have this error with application develloped with Java and runing on docker container.  In addition to that, before creating this issue, we had already contacted  the support azure and we  had many meetings  to check our network; everything seemed fine they didn't detect anything unsual.
The information of the azure support ticket bellow.
 - Timeout when using the application gateway ... - TrackingID#2402210050003918 

Out of the different meetings we had with the support, the conclusion was that it is not a net work issue.

@fanemama, let me prepare a setup (SB resource behind app-gateway and SDK consumer running in a Docker instance) to see if this can be reproduced.
