[SOLVED] Incorrect host in Spreed.me iframe

I am trying to get Spreed.Me to work, but for some reason can’t get it sorted.

The main page opens, and on top it shows Initialising but it never ends. When checking the iframe details I can see:

<script id="globalcontext" type="application/json">{"App":"main","Cfg":{"Title":"Spreed WebRTC","S":"static/ver=0281","B":"/webrtc/","Token":"f341f72e7a5993b3cdebbaa6afa4bdfe5cb985f1e2d595bc253e5f10403ea24a","Renegotiation":false,"StunURIs":[],"TurnURIs":[],"Tokens":false,"Version":"0.28.1","UsersEnabled":true,"UsersAllowRegistration":false,"UsersMode":"sharedsecret","DefaultRoomEnabled":true,"Plugin":"extra/static/owncloud.js","AuthorizeRoomCreation":false,"AuthorizeRoomJoin":true,"Modules":["screensharing","youtube","presentation","contacts"]},"Host":"192.168.7.245:8080","Ssl":false,"Csp":false,"Languages":["en-gb","en-us","en","nl"],"S":"static/ver=0281"}</script>

I would have expected that ‘host’ should be https://<domain>

Can somebody give me any directions?

OK I resolved it. I put the proxy details in the wrong web-server (I have NC behind a Apache proxy)
