We have a mobile application (iOS & Android) that makes real-time communication with our API through SignalR.
There is one single case where the SignalR Hubs were not functioning in a platform where Nginx was used as a reverse proxy. We found and applied the "X-Accel-Buffering: no" http header solution as defined in https://github.com/dotnet/AspNetCore.Docs/issues/10827.
Now the problem is gone in iOS Devices, but not in Android. Has anyone experienced a similar issue?
