VisualVM无法使用service：jmx：rmi ///连接到178.xxx.xxx.xxx:xxxx

Question

I used visualvm last week on my notebook and it worked without any issues. When I wanted to use it yesterday I get the error: VisualVM Cannot connect to 178.xxx.xxx.xxx:xxxx using service:jmx:rmi///... once adding a jmx connection.

The odd thing here is that I have the same version of visualvm, java jdk, java security level, internet connection and windows 7 professional on the desktop computer where it still works.

• firewall disabled (didn't work)
• port forwarding (not needed as it works fine on the desktop computer with the same connection)
• additional firewalls or anti virus software is not present

The notebook is a dell and a few days ago it got a major bios and dell util update, but I don't think this should fall into account in this matter.

Do you have any idea what else it could be, or what else I could do to track down the issue?

FYI I have another WIN7 home computer where it still works and a partner reported that he is getting the same issue for some time now on his desktop and notebook. I'm really at the end of my expertise :(

Answer 1

Seems like network environment issue. You may trace the other port first. (like 80 port)
