Hello there, I have .Net Core 3.1 API application with client side technology as Angular 7 and i am trying to use SignalR with Redis setup like mentioned below
Angular side
And i am using Group at backend to hold the logged in user like below
With above setup everything is working fine though when client side tries to reconnect with signalr it gets failed and we are not able to receive any kind of message from backend not sure why. Any help regarding the same is appreciated.
Client side is trying to reconnect with signalr after some time with negotiate call and gets new connection and thats when it starts failing to receive/send message over signalr. We have disabled stickiness for load balancer and target group as well though its not working for single server also. Below is the screenshot showing how signalr is reconnecting and unable to receive message

Anonymous2023-04-14T10:10:17.77+00:00 Could you please tell me how you host the application? It seems you have load balance for your application? What's the load balance settings for it? If you are using the IIS ARR, I suggest you could try to use FRT at the ARR server to check if there is network issue firstly.
