Hi, as title says, when i connect a new site with newt i am not able to complete the connection due to ping fails.

I am currently on a hetzner VPS with the following firewall rules:

  • Allow any request on any port from personal public ip
  • allow ICMP from personal public ip

Here are the logs from pangolin
