I am currently setting up Cloudron on a VPS at Netcup and ran into an issue with the Netcup DNS integration.

My Netcup account uses CloudDNS. The domain is configured with the current Netcup CloudDNS nameservers:

netcup.firstns.cc
netcup.secondns.at
netcup.thirdns.de
netcup.fourthns.systems
netcup.fifthns.com

Cloudron 10.0.3 does not initially recognize these nameservers as Netcup nameservers. The current implementation in src/dns/netcup.js appears to still check for the legacy Netcup nameservers / dns.netcup.net.

I temporarily modified this check to accept the current CloudDNS nameservers. After doing so, the next error was:

Netcup DNS error [5028] Can not update (all) DNS records for zone.
The zone hallecloud.de could not be found.

After looking into this, it appears that the current Cloudron integration uses the legacy Netcup DNS API.

Netcup now distinguishes between:

Legacy DNS: Legacy API Key + Legacy API Password
CloudDNS: API Key

My CloudDNS account therefore provides a CloudDNS API key, but does not have the legacy API credentials expected by the current Cloudron integration.

The Netcup documentation also appears to confirm this distinction.
My questions:

Is support for the current Netcup CloudDNS API planned for the Netcup DNS provider in Cloudron?

If not, is there currently a recommended way to use CloudDNS with Cloudron through the current API?

As a workaround, I switched to Cloudflare.

However, native CloudDNS support would obviously be much more convenient, especially because Cloudron could then automatically manage DNS records when installing applications or making DNS-related changes.

It seems that the existing Netcup integration would primarily need to be adapted to the new CloudDNS authentication method and the current CloudDNS nameservers.

Thank you for looking into this. I would appreciate any information on whether CloudDNS support is planned or whether there is another recommended approach.

Best regards
Lukas
