Hi @Abhishek M ,
Azure SignalR is designed to maintain persistent connections between the service and clients, see https://video2.skills-academy.com/en-us/azure/azure-signalr/signalr-concept-internals. There aren't any built-in methods; that I'm aware of, to notify or wake disconnected clients. There may be various reason a client can be disconnected as document in https://video2.skills-academy.com/en-us/azure/azure-signalr/signalr-howto-troubleshoot-guide#client-connection-drops; however, any type of connection re-establishment would have to be handled on your client side.
