Hi Rob,
thank you for your fast answer ;-)
I tried to add some nodes manually, without any changes. I also give the Wallet some hours for a connection, but there is absolutly silence.
Sometimes i got a single connection for one or two seconds to different random nodes in the "Tools -> Peers" Tab.
I have to change my Timezone? Actually the Time / Timezone is correct set for my Country.
Here are the last lines from the Log. Maybe anyone can see the Problem?
