Lync 2013 - ipad

Hi,

I have a lync 2013 environment setup along with a reverse proxy server for mobile users.

Desktop users can sign in fine using the 2013 client, however apple devices are unable to sign in unless they use the 2010 application.

Is this down to settings on the server or somethign that needs changing on the apple devices?

If i try to sign in using the  2013 application it states: ‘Cant connect to the server. It may be busy or unavailable. Please try again’

Thanks

This is a known issue:


Take a look here for the resolution:

Are iOS device the only mobility clients which cannot connect (meaning Android and WP8 work) or are those the only mobility client's you have tested?

If the latter than you probably do not have the correction configuration allowing traffic hair-pinning to the reverse proxy.  the requirements between the 2010 and 2013 clients are quite different.

See this article for more details:

Mnay thanks.

I have the server root certificate installed ont he ipad along with the Front end certificate.  

The front end certificate is added to the bindings on the Reverse proxy server already and the front end server.

I will look into the hair pin rule on the firewall and let you know the outcome.

Thanks
Hi,

The hairpin rule was added to the firewall and the same issue is happening.  I removed the hairpin rule as it seemed to prevent 2010 app signing in, now both 2010 and 2013 apps are unable to login.

The issue was down to an IP trypo in the firewall rule.
