Dokku website not reachable from ipv6-only machine
Closed this issue · 9 comments
Description of problem
I just started using dokku on a Hetzner cloud server, which I had configured to use ipv6 only.
The wget to the dokku install script always failed with "network is unreachable" (other wgets to e.g. the dokku logo as well). Once I added ipv4 to my cloud server I could connect.
It seems that your website is not supporting ipv6 connectivity (AAAA records): https://www.nslookup.io/domains/dokku.com/dns-records/
Steps to reproduce
- configure a host to ipv6 only
- perform "wget https://dokku.com/install/v0.33.3/bootstrap.sh"
dokku report $APP_NAME
n/a

If I add AAAA records, how can I test that the site is reachable from ipv6?
website has SSL issue for me as well
If I add AAAA records, how can I test that the site is reachable from ipv6?
Maybe with this? https://ready.chair6.net/?url=dokku.com
BTW for testing connectivity to v4 or v6 only website you can use:
- ipv6.google.com
- ipv4.google.com
PS github doesn't support ipv6 yet: https://isgithubipv6.live/
@killa-kyle you almost certainly aren't seeing the same issue, as this covers "not reachable" issues, not "curl protocol errors". Please open a separate ticket so we can track that.
I setup an AAAA record pointing at the new IPv6 ip for the dokku server. Do you mind checking it out @tauinger-de ?
Looks fine! I could connect from my Hetzner server and the other two online tests are positive, too.
Nice! Closing :)
