I am using Nginx as reverse proxy with the following configuration file.
There is one endpoint at 127.0.0.1:8081 which creates a websocket connection. Almost every endpoint is secured by a JWT authorization.
When I am sending requests to the HTTP endpoints everything works fine and the Authorization header gets forwarded to my backend application. It just does not work when requesting the websocket endpoint. The Authorization Header is null then so it gets kinda cut from Nginx or something like that. When I remove the required Authorization in my backend application the websocket connection and the http endpoint both work perfectly fine. It's just the Authorization Header when calling the wss://domain/chat.
Does anyone have an idea why this is happening?
