We have just upgraded from v15 to v15.5. I am trying to get the webmeeting to work. The link to https://xxxx.3cx.net/webrtc/open/xxxxx works fine, and we get the page for the 'guest' to log into the meeting. Once clicking on 'Log in' we get the message "Can't connect to https://DOMAIN:443/myphone'. DOMAIN resolves correctly both inside and outside to the correct addresses. I don't see anything in the 'myphone' folder that provide any services. Where do I need to go to confirm/correct this connection URL?
