Skype for Business Web SDK samples not working

Question

I have downloaded the Skype Web SDK samples from here, but I can't make them work. I have registered a trial Office 365 account (dotnetsolutionsdemos.onmicrosoft.com) and I have a user there ([e-mail]).

If I run the desktop version of Skype for Business then I can log in with my account so it seems that the Lync service does work.

I have installed the Skype for Business Web App Plug-in, put the sample code under IIS and opened it via a browser. Then I tried to sign in with my aforementioned account and it doesn't work. The ajax loader image is displayed and never disappears.

Upon inspecting the network traffic, I found the following:

There is a GET request to https://lyncdiscoverinternal.dotnetsolutionsdemos.onmicrosoft.com/xframe which fails. The request fails with some name lookup failure or something, doesn't even return an HTTP response.

There is another request to https://lyncdiscover.dotnetsolutionsdemos.onmicrosoft.com/ which returns 403 Forbidden.

Upon navigating to this address I find that the SSL cert doesn't match the URL.

I have tried it with IE/Chrome/Firefox, all the same. Also I haven't configured anything after registering the Office 365 account just used the default settings. As I said the desktop Skype for Business logs in just fine.

What am I doing wrong, how can I make this work?

Please find captured images below.

Currently the Skype Web SDK doesn't support Office 365 accounts - only on-premises or hosted (in a Data Center. etc.):

Microsoft have indicated that Office 365 will be supported, but haven't yet provided any public guidance as to when as far as I know.

I'd recommend keeping an eye on the MSDN forums for updates on when this will be supported.
