Hi
Quite new to traefik so am hoping to get some help setting up a working container with traefik.
I use the Danish DNS provider gratisdns.dk
from acme.sh there is a 3rd party provider dns_gdnsdk.sh that works.. in a seperate docker with just acme.sh I can pull a certificate .. all good.
But getting traefik to pull a certificate is proving to be very difficult..
My docker-compose file is built from examples and I've change very little apart from trying to replace cloudflare with gratisdns..
I am hoping someone can help 
running the below file gives me the following error:
level=error msg="Unable to obtain ACME certificate for domains "vandelay.dk,*.vandelay.dk" : cannot get ACME client unrecognized DNS provider: dns_gdnsdk" providerName=dns_gdnsdk.acme
I've tried all sorts of iterations. I've added the dns_gdnsdk.sh file to the acme folder... I've scratched my head fervently for a few days.. nothing seems to work.. I expect fixing this error will lead to another..
I tried replacing staging server 02 with 01. which provided another error...
version: "3.7"
