Original GitHub issue: https://github.com/NginxProxyManager/nginx-proxy-manager/issues/3863

I run npm v2.11.2 on Ubuntu 24.04.

I had ipv6 enabled but then I disabled it.

Container wouldn't start.

Then I added

    environment:
      DISABLE_IPV6: 'true'

Container started. Created a host but couldn't get a SSL cert. Internal Error.

Then I re-enabled ipv6, removed the line from yml file.

Everything is fine now.

The VM on which Nginxproxymanager runs is behind a Mikrotik that assigns an ipv6, but I don't use that becasue it doesn't work anyway. I couldn't get on the internet using ipv6 only.

Hello got same issue, which DNS are you using ? If its cloudflare, desactivate cloudflare proxy (test but wait a few minutes), get your ssl certs and put cloudlfare proxy again.
Otherwise for other DNS use nslookup <your_domain> and verify its your ip.
