I am running httpd-2.4.6 on CentOS7. I have an https virtual host configured to proxy requests to a specific location as wss
However, attempts to connect occasionally fail, using curl to test:
curl -i -N -H "Connection: Upgrade" -H "Upgrade: websocket" -H "Protocols: stomp" https://127.0.0.1/ws
-H "Sec-WebSocket-Version: 13" -H "Sec-WebSocket-Key: asdfghjkl;qwertzxcvbnmlk" -k
A failure results in:
curl: (52) Empty reply from server
Has anybody else seen this behavior or have any suggestions? Updating to a version of httpd not in a Centos repo is not an option for me, unfortunately.
Any help is appreciated.
