I have been trying to set up a webserver on a subdomain, since I can’t open port 80 on the webserver I can’t use the usual method for provisioning certificates, so I have to use the DNS method  
Are there any existing plugins for this?  
Would adding a DNS provider for which there is a plugin as a secondary DNS do the trick?

As far as I know they have stopped developing official plugins, I also have figured out the answer to the second question, no
