Webstorm debugging issue

My web server suddenly stopped debugging in Chrome. Port and settings are correct, or they seem to me. This worked until two days ago, but stopped working today. I tried to trace any changes to the car, but none of that would have affected. So here's what's going on -

I run debug, it launches chrome, the jetbrains top debug bar is displayed in the browser and closes as soon as the project is loaded. So far, I created a new test proj, reinstalled WS, JRE, JDK, replaced the JRE folder inside the WS folder, rebooted my computer, but to no avail.

I have looked through the log files and this is what it generates -

I can confirm that upgrading to Webstorm v9 EAP solved this problem for me:

http://confluence.jetbrains.com/display/WI/WebStorm+EAP

I had the same symptoms. Debugging took place a couple of days ago with webstorm 8.04.



My Chrome should be automatically updated. At the time of this writing, I had chrome 38.0.2125.101 and webstorm 8.04 was not compatible with it (it seemed to start debugging OK, but then accidentally said that the browser was disabled after about 5 seconds).

After upgrading to Webstorm v9 from the EAP link above, I can debug again.
