Extension in Loadbalancer Setup / DNS Challenge

[fruske]

Assuming the case you have a loadbalancer(LB) listen to www.example.com and distributing requests to www01.example.com and www02.example.com which are stored at different servers running plesk.

There is currently no way to make the extension work that way. The challenge is only solved if you luckly where redirected to the correct server from the LB.

You can set an domain alias for www01. and www02. but still for the certificate for www.example.com you need luck.

For the initial SSL setup this try and error approve works but not for automatically renew process.

Either it should be possible to allow a DNS challenge in Plesk Lets Encrypt extension or maybe there is an other solution i currently cant see.

DNS challenge would be awesome. I think this would resolve the problem with lists/mail/webmail subdomains (https://tools.ietf.org/html/draft-ietf-acme-acme-06#section-8.4)
