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)

That is strange indeed. so curl -6 https://ipv6.api.cloudron.io/api/v1/helper/public_ip does not work on this server? If so then clearly the server is not correctly set up for ipv6, we should check then what is missing.

@nebulon

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?

so at least it has resolved it then, this means the ipv6 routing is not working as expected. Something wrong with the server setup in Hetzner then.
