can't not access configuration utility

Hello guys, I know this is an old topic, but it's in my subject.

I'm running 10.2.3, and surrendly my Configuration utility stopped to run. SSH is OK, the box is running fine but I can't access configuration utility. Chrome doesn't give me any error... the website just try to load.

By SSH I could see activity on port 443(tcpdump), and Catalina is showing a "No access" error. What should I do? Restart tomcat? Does anybody see that before?

Thanks.
