@JOduMonT Currently, Cloudron does not support IPv6 and requires an IPv4. You can, of course, configure your server to have IPv6 address additionally and configure DNS AAAA records manually and that should work. Goes without saying, we want to add IPv6 support at some point (I know it's 2020!! )

Hi @derek sorry for the delayed answer, did you manage to solve this after the TTLs have expired from your attempts?

Ah seems to be working now thanks - I had added my full domain foo.ddns.net to the zone name field initially as It autofilled ddns.net and I thought that cloundron might then try to generate subdomains with the foo part missing e.g. my.ddns.net which wouldn't work but apparently not. Thanks for the Help!
