Do we have any idea how long it might take to resolve this issue?
Usually, we do not provide any ETA on forum. Our working hours is 10:00-20:00 GMT+3 at workdays.
We checked your server. Seems like WCS cannot listen default websocket ports
because these ports are busy by Apache
If you need to proxy websocket ports, you should change Apache settings to ports 80 and 443 respectively (in this case websocket URL will be
for client connections) and set up proxying to WCS ports 8080 and 8443. Another option is to change WCS default ports
and set up proxying to these ports.
Both Apache and WCS needs to be restaerted after settings changing.
If, however, you do not need to proxy websocket ports, just stop Apache and disable it.
systemctl stop httpd
systemctl disable httpd
