问题
The following screenshot has been showing up for several days now. Are other people seeing this?
Note: to be sure it were not a general connection error, in addition to being able to post this sof message i did a github pull. That is a solid indication that my network proxies have been properly disabled: and it worked fine. So the message is puzzling.

Possibly a known bug fixed in Intellij IDEA 13.1 (27 Mar 2014).
- Go to Settings / Updates, then press button "Check now".
- Result: normal Update info.
Un-checking Use secure connection in the above mentioned window may fix the issue under some circumstances.

To fix this problem:
- Select Settings / HTTP Proxy
- Select the radio button: Auto-detect proxy settings or simply No proxy
If select Auto-detect proxy settings:
- Select check box for Automatic proxy configuration URL: and enter your proxy URL
- Select Check connection button
Worked for me!
