When I click the "Help/Check for updates" link in IDEA 15.0.1, I get this error in a popup. I have to go through a corporate firewall, but I have verified that I can get to HTTPS: sites in a browser and also using the "Test Settings" button in the IDEA settings page. IDEA also shows that it has stored the certs for download.jetbrains.com, plugins.jetbrains.com, and www.jetbrains.com. No idea what's causing this particular hiccup. Anyone have any insight on this?
