Vu+duo network trouble

Hi,
I have a strange problem with my Vu+duo running Open Pli.....
When i do a network test on the Vuduo all is ok except by LOCAL it says disconnected and by NAMESERVER it takes a while but after some seconds it tells CONFIRMED.......
Some time ago this was all ok but not now.....
Also when i try to download new available plugins it says:Can't connect to remote host.....and a time out happens....
What is wrong?
I have checked my router but can't find the problem there...
thx and i really hope someone has te right answer for me....

Solved !!
Needed to reset the router and fill in all the details again....Works fine again now....
