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
