iPhone Skype for Business Login Error: Can't Connect to Server

As a business, it's essential to have reliable communication tools that enable seamless collaboration among team members. However, when errors occur, they can hinder productivity and cause frustration. One common issue faced by iPhone users is the inability to sign in to Skype for Business due to a 'can't connect to server' error.

In my case, I've observed that Windows phones and Android devices work perfectly fine through both 3G and Wi-Fi connections. However, when iOS clients experience issues signing in, the Web Ticket service response may appear as follows:

Ĭonst std::string MEX_ATTRIBUTE_VALUE_WIN_NEGOTIATE(“ WinNegotiate“)

Ĭonst std::string MEX_ATTRIBUTE_VALUE_WEBTICKET_BEARER_TOKEN(“ WebTicketBearer“)

Ĭonst std::string MEX_ATTRIBUTE_VALUE_FED_BEARER_TOKEN(“ FedBearer“)

To resolve this issue, it's essential to understand the available authentication options. The Lync mobile application retrieves the MEX bindings from the Web Ticket Service and expects to see WebTicketServiceWinNegotiate from the available authentication port names. Specifically, the iOS clients will hang during the sign-in process, and the cancel button is unresponsive.

It's important to note that iOS clients do not support basic NTLM Authentication, unlike Windows Phone and Android clients. Therefore, if both Windows Phone 7 and Android devices can successfully login, but iOS clients cannot, it may indicate a specific configuration change applied to the Lync servers at some point.

Troubleshooting Lync client connectivity can be challenging when dealing with multiple clients exhibiting different behavior and scenarios where not all clients can sign in successfully. To resolve this issue, it's crucial to identify the root cause of the problem and implement the necessary fixes.

By understanding the authentication options and identifying potential configuration changes, you can troubleshoot and resolve the 'can't connect to server' error on your iPhone Skype for Business app and ensure seamless communication with your team.
