Answer questions mkArtakMSFT

Thanks for contacting us, @kmuthukumar23. This looks like an issue with the actual load-balancer/gateway you're using, which ends up dropping the connection. If this is the case, Azure SignalR service would definitely help. Can you give this a try? Is that a viable option for you?

@anurse do you have any guidance for these types of situations?

useful!
