Skype for Business on iOS

I am having issues getting Skype of Business to open on iOS with my internal lync 2013 setup. A few years ago I was able to install the cert from the lync server onto an iOS device but this no longer seems to be working.

When I attempt to sign in I get the message "We can't connect to the server. Check your network connection, advanced options and try again."

I have had a user try this on android and it downloads and installs the cert and works without issue. This is only happening on iOS it seems.

I am only trying to get this to work on my internal network, external access will be down the road. Any help with this would be great!

If you have other applications on the device I would make sure those are updated. And that you have the latest version of IOS installed. Next try rebooting the device. Also check the router and Internet connection. Hope this helps.

I was finally able to get this working via the following link

What fixed this issue from my iPhone for me was going to Settings -> General -> About -> Certificate Trust Settings, and there is a section called "ENABLE FULL TRUST FOR ROOT CERTIFICATES". Under it lists the certificate that I installed on my iPhone. Once I enabled that, I'm good to go.
