Hi, I am running newt in an lxc on proxmox. When trying to connect to pangolin i get 5 connection timeouts:

apparently newt is able to connect to the vps an pangolin but isn't able to connect to the gerbil wireguard container in docker. Checking the logs of gerbil gives me multiple errors where gerbil isnt able to connect to the pangolin container:

ERROR: 2025/03/13 21:20:22 Error fetching remote config http://pangolin:3001/api/v1/gerbil/get-config: Post "http://pangolin:3001/api/v1/gerbil/get-config": dial tcp 172.18.0.4:3001: connect: connection refused

I tried checking if the communication between these two containers is possible at all and i didn't encounter any
errors so I have no idea how to troubleshoot further:

for recreation:

  • Install pangolin on vps with wget script
  • Install newt in docker or lxc with given istallation scripts from the documentation
  • Try connecting, realise that port 51820 may not be open on vps try opening with ufw
  • keep getting connection errors

would be greatfull for tips

couldn't solve it. might have been a problem with the vps provider IONOS. Was able to cancel the subscription. I am now using netcup and it works fine
