Hi Ocelot Team,
Please give advice for my current issue when using Load Balance configuration on Ocelot Gateway. My websocket implementation is for Microsof SignalR on my web client
## Expected Behavior / New Feature When one of server is down, not causing error and able redirect request to connect websocket to another server
Actual Behavior / Motivation for New Feature
1 Backend Server down causing Bad Gateway request and unable to a connect websocket to another backend server
Steps to Reproduce the Problem
- Server A installed with 1 Backend service (using .net core 3.1) and Gateway (Ocelot) service
- Server B installed with 1 Backend service
- When All service running, client able to connect websocket using gateway
- When Backend service is turned off on Server A and backend in server B is running, client unable to connect websocket via gateway
- When Backend service is turned off on Server B and backend in server A is running, client unable to connect websocket via gateway
- Http request is running fine.
Specifications
- Version: Ocelot 16.0.1
- Platform: .net Core 3.1
- Subsystem:
