All of a sudden IntelliJ is telling me this:
There's no other way but to kill the process. I can't even get to the setting to prove that proxy is still on nor to the IntelliJ's logs.
There should be some way how to keep working (a day?) when the license cannot be validated. It effectively stops my work now.
Button "yes" can't contact the server. Button "no" won't let IntelliJ continue (infinite loop).
