Connection with websocket via apache not established

Question

I configured httpd.conf for websockets, I can’t establish a connection, I get a “status line for reading errors from the remote server” The following are the errors and configuration.

Configuration

<Location /socket.io/> 
ProxyPass http://172.27.38.93:9090/socket.io/
ProxyPassReverse http://172.27.38.93:9090/socket.io/ 
</Location> 
<Location /socket.io/1/websocket> 
ProxyPass ws://172.27.38.93:9090/socket.io/1/websocket 
ProxyPassReverse ws://172.27.38.93:9090/socket.io/1/websocket 
</Location>
