Quick Tip: iOS Client won’t login

This is the first of my quick tip items – less in-depth analysis and more “how to fix”.

Scenario: Lync iOS user running iOS 7.x, connected via wireless connection.

Issue: User was unable to login to client.  They were met immediately with a “unable to connect to server” error message.  We found that if the user were to move to another wireless connection they were able to login without any issue.

Log File: Upon review of the log file I found several messages like the following:

Failed to get http proxy setting using http://wpad/wpad.dat for UcwaAutoDiscoveryRequest for user@domain.com

This would happen about 10 times through out the single login experience.

Solution: The device was attempting to discover corporate proxy settings due to settings on the client.  Within the Settings | Wi-Fi on the iOS device.


Change HTTP Proxy from Auto to Off.  The WPAD errors immediately went away and the device was able to connect without issue.

    Thanks Richard. You are awesome. I just did this and had the info in the log file compaining about wpad blah blah. We turned it OFF and the client signed right in. No reboot or anything needed. I’ll be adding this to my FAQ as well.
