This is what I set:
upstream for_ssl {
server 127.0.0.1:1234;
}
proxy_pass http :// for_ssl;
The following is the error:
400 Bad Request
Sec-WebSocket-Key not found.
This is a WebSocket service and can not be accessed via HTTP.
Please give me some advice. .
nginx has the concept of protocol upgrade when acting as a proxy for long connections
With this code, there will be no problem and protocol upgrade is allowed
