Hi Francis, Many thanks for your message and for your help, it’s very kind of you. As you suggested, I’ve tried to add these lines on the “black box” side: proxy_set_header Upgrade $http_upgrade; proxy_set_header Connection upgrade; proxy_http_version 1.1; But unfortunately, without success, these lines didn’t improve the websocket connection. So, I’ve decided to rollby YAGA - Nginx Mailing List - English
Hello, I’ve a websocket (wss) connection issue (status 200 instead 101) between a “server” (running nginx/1.14.2 reverse proxy) and a “black box” (running nginx/1.8.1 web server with websocket). The “server” has access to Internet and to the local network where is connected the “black box”. I called it “black box” because I can’t change anything except the nginx confiby YAGA - Nginx Mailing List - English
