Hi! After a change of connection point (the same ISP but different location, but with the same wireless, and end-points)
the tunnel no longer is established. Nothing in the wg configuration is changed ...
from the "client" machine to the "server" end-point i can do:
root@hal: ~ # nc -u -vz sev.HHHHHH 43333
Ncat: Version 7.80 ( https://nmap.org/ncat )
Ncat: Connected to HHH.HHH.HHH.HHH:43333.
Ncat: UDP packet sent successfully
Ncat: 1 bytes sent, 0 bytes received in 2.01 seconds.

How can i debug further to see why the connection is not established?
Thanks a lot!
Adrian

i apologize for the noise! the problem was a typo on the server configuration
where a peer was defined also with it's endpoint (dynamic) dns name.
this worked fine as long that name was resolving correctly but as soon as this
failed the connection could no longer be established.

Thanks!
Adrian
