IntelliJ IDEA Ultimate 2017.2 keeps asking proxy credentials

Question

I am behind an enterprise firewall, have checked "Auto-detect proxy settings" in System Settings -> HTTP Proxy. I entered the correct credentials and checked "Remember". I know the credentials are correct, as I am able, for example, to download and install plugins.

However, IntelliJ keeps asking me periodically to re-enter the proxy credentials. Why?

Answer 1

For me the solution was changing proxy setting to "No Proxy" from "Auto-detect". Idea retrieves proxy settings anyway from Windows.
