Cannot connect NXV-300

Metso

Hi,

Probably after latest Java update I cannot anymore connect to a NXV-300. Have tried with IE11, Firefox35 and Chrome40. Java is version 8 update 31 (Win7). I have added the ip of the NXV-300 in the Java Control panel to Exception Site List.

This is the error message I get from Java Console:

Java Plug-in 11.31.2.13

Does anyone know how to solve this problem?

Have you tried to use a standard VNC client? Just grab UltraVNC and connect to the IP of the NXV300 direct.

I gave up on the integrated java clients on any system back in 2006

edit: Often the NXV300 locks up and stops accepting connections and needs a restart

I too vote for the NXV lock up. Power cycle it before you go too crazy trying other things.

And the result of power cycling?
