<![CDATA[FAQ: ping6 -q -c 1 api.cloudron.io isn't returning an IP address.]]>Mmmh.

  • Instance is: hetzner location USA. IPv4 & IPv6 activated, RDNS set.
  • No firewall set: hetzner & VPS. Cloudron 9.0.x (x=18)
  • Default Cloudron network set to Configure IPv6 = Public IP
  • App install quits with error (something like) can't detect ipv6 adress

Shell shows:

ping6 -q -c 1 api.cloudron.io
PING api.cloudron.io (2604:a880:800:10::b66:f001) 56 data bytes

--- api.cloudron.io ping statistics ---
1 packets transmitted, 0 received, 100% packet loss, time 0ms

Any idea to solve the problem?

(My solution was: Configure IPv6 = Static IP -> problem solved)

It's fixed now.

Something wrong with the server setup in Hetzner then.

curl -6 https://ipv6.api.cloudron.io/api/v1/helper/public_ip 
curl: (7) Failed to connect to ipv6.api.cloudron.io port 443 after 5139 ms: Couldn't connect to server

More ideas?

If so then clearly the server is not correctly set up for ipv6, we should check then what is missing.
