I have been using dude 4.0 beta 3 for monitoring network and work great, i saw that there is newer version 6.x.x and i installed it but it wont work for me, just shows message not connected, tired few 6.x.x version and none of them is working for me, i installed again version 4.0 beta 3 and work fine.
Any idea how can i fix this problem with newer versions?
Wait some more time till the new dude will be usable at least like the old one. You can try it time to time without any impact on your actualy running dude instance.
