I have an internal acme-dns server.
It seems not possible to register accounts inside the GUI. However I have registered an account on the acme-dns server with an other acme-dns client. When I try to use that account in the GUI I got following error message in the logs:

12/19/2024, 9:07:39 AM, info, orders/fulfilling_do.go:100, orders: fulfilling worker 0: order 4 done
12/19/2024, 9:07:39 AM, error, orders/fulfilling_do.go:99, orders: fulfilling worker 0: fulfill auths error: invalid scheme () in http client request url (acme-dns.irf.se/update); is an acme directory failing to fetch?
12/19/2024, 9:07:39 AM, error, challenges/solver.go:75, challenges: deprovision failed (invalid scheme () in http client request url (acme-dns.irf.se/update); is an acme directory failing to fetch?)

I'v tested the account with the acme-dns client and it works. Updates are also allowed from the Cert Warden address I run the server on.
It seems to be a scheme problem. Cert Warden seems to use http, but I've configured so that https must be used to the acme-dns server. Am I correct?
