Hi, I have a problem from past few days. Simply my connection with webpage stopped working.

I can connect with web page only like those: - localhost:8080/App - IP:8080/App

What's really bothers me is that from localhost there is no issue - everything seems to be fine. However when I try to connect by IP from the same machine or from other computer I'm getting:

I'm quite lost for past few days on how to repair this - especially that it was working fine for last 2 months.
