I've got Version 7.21 and the system tells me that it's up to date. So that shouldn't be the cause of the problem either (after all, the node ran on the older versions...)?
Rebooting the Raspi didn't help either.
Another screenshot, maybe it gives you another idea?
-I just reinstalled the nodes, no difference.
- Then I entered a wrong password on purpose --> I get the same message "Services received" - so that doesn't seem to mean anything. Maybe it's the 49000 <-- this is the port, i guess. Is there a way to see if it's the right one or change it in the fritzbox to 49000? That might work, I have no other ideas at the moment...
- I tried a few of the other nodes (due to a lack of information without really knowing what I was doing...). Maybe this gives anybody a hint of where the problem is?
