Use mod_proxy_wstunnel

	Enable mod_proxy_wstunnel module to set WebSocket Proxy.
[1]	For example, configure httpd to set proxy on /chat for an application which listens on localhost:1337. The sample application is from here (section [3]).

[root@www ~]#  vi /etc/httpd/conf.modules.d/00-proxy.conf # add to the end LoadModule proxy_wstunnel_module modules/mod_proxy_wstunnel.so [root@www ~]#  vi /etc/httpd/conf.d/wstunnel.conf # create new ProxyRequests Off <Proxy *> Require all granted </Proxy> ProxyPass /socket.io/ http://127.0.0.1:1337/socket.io/ ProxyPassReverse /socket.io/ http://127.0.0.1:1337/socket.io/ ProxyPass /chat http://127.0.0.1:1337/ ProxyPassReverse /chat http://127.0.0.1:1337/ [root@www ~]#  systemctl restart httpd

Access to the sample App to make sure it works normally on proxy environment.
