I am having trouble setting up chromecast with Orcon.

Chromecast sees router and accepts password and then tells me that there has been a "whoops" the set up has no problems until then.

Any how I cannot see in the Orcon router menus any particular area that needs adjusting.

Is it just Orcon and chromecast are a problem. Orcon help aren't interested in giving advice.

Is there a way around to get it to work?
