Intellij check for updates: unable to connect

Question

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.

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!

The prior answer already solved the problem - but your answer seems to provide useful info for others looking here so I will upvote in any case. – WestCoastProjects Jan 22 '16 at 17:52
default setting was 'No Proxy' when the error occurred, in my case; 'Auto-detect Proxy' did it for me (while keeping everything as default). – 7kemZmani Sep 12 '17 at 21:33
This answer worked out for me on my windows machine. – Jai Prakash Mar 06 '19 at 00:38

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.

I just manually installed IntelliJ 13.1.4, same problem there when checking for updates: Connection failed. – jpsecher Sep 17 '14 at 10:59
Doesn't work for me either, 15.0.2 ultimate, on a VBox VM inside Windows 7 on an intranet. But all connectivity from the VM to the outside world works fine. – Raul Santelices Jan 08 '16 at 13:56
@RaulSantelices **uncheck** `Use secure connection` in settings -> updates – Pejman Aug 07 '17 at 23:20
