This is one of those things that I find I constantly have to google. Oftentimes app traffic will just not flow correctly, more often than not the issue is with an outdated proxy setting. What trips one up here is the fact that this proxy is not listed in your IE proxy settings. The issue is that the winhttp proxy component has been set – below is how we can manipulate it.
View Current Proxy Settings
- Windows Vista / 7 / 8 command line: netsh winhttp show proxy
- Windows XP command line: proxycfg
Reset Proxy Settings
- Windows Vista / 7 / 8 command line: netsh winhttp reset proxy
- Windows XP command line: proxycfg /d
Simple fix to a potentially frustrating problem!
