I am setting up a GeoDNS SSL validation system for my domain names. It turned out that some hosts have some limitations with the way they setup the HTTP-01 challenge within their plesk setup. Allegedly it will not honor redirect rules for http://<YOUR_DOMAIN>/.well-known/acme-challenge/<TOKEN> to go back to the apex.
Is there an undocumented mechanism to have the challenge be made over a different folder than /.well-known/acme-challenge/?
If not, this should surely be a top feature request.
This setup you are trying to implement is not possible on our server because there is a higher-ranking (serverwide) RewriteRule regarding the .well-known/ folder of any domain which is needed for the SSLit/Let's Encrypt plugin
They are using a plesk UI setup on a nginx server proxied through apache.
Now I am looking into maybe instead implementing a DNS-01 challenge or is there a better way for me to do this?
That sounds like they support a LetsEncrypt integration themselves, in a manner that prohibits their clients from using ACME.
I would ask them if it is possible to leverage their LetsEncrypt plugin for your needs. If not, you will have to use the DNS-01 challenge, as their server rules will take priority against any redirect or location rules you try to implement.
