Blocking * ingress IPs breaks CF Tunnels

I use a Hardware firewall (Hetzner), but when I block all ingress IPs (following the Docs), the tunnel state immediately goes down.
Starting log stream it shows that the connection fails and starts retrying periodically.
(Log stream does not immediately disconnect)

I tried looking for IPs and Ports to whitelist on the hardware firewall, but to no avail.
What IP addresses and Ports should i excempt from my ingress traffic block?
