If I'm using a single swarm box to manage apps on 2 different domains, if the 2 domains are not able to be verified using the same dns challenge method, what else could one do?

this is a feature request/question if something like that would be possible?

I think this might be possible by adding another certresolver:

I also stumbled upon this but haven't tested it yet

Multiple DNS challenge provider are not supported with Traefik, but you can use CNAME to handle that. For example, if you have example.org (account foo) and example.com (account bar) you can create a CNAME on example.org called _acme-challenge.example.org pointing to challenge.example.com. This way, you can obtain certificates for example.org with the bar account.
