    You can also create a link from httpsdocs/.well-known to httpdocs/.well-known and keep option 'Run the website in compatibility mode for the legacy option "Separate SSL/TLS and non-SSL/TLS content"' enabled. This solved issue "The authorization token is not available at https://domain.tld/.well-known/acme-challenge/*** . To resolve the issue, make it is possible to download the token file via the above URL.".

    We also had a problem renewing the Let's Encrypt certificates. This was because we where having a URL rewrite rule that automatically redirected all requests from HTTP to HTTPS, As written above "Let's Encrypt creates temporary files in the depths of the domain's document root in order to create a certificate and verify that you own this domain". This temporary folder is named ".well-known". We excluded this folder from the rewrite rule, now Plesk Let's Encrypt extension is working properly. So add an exclude and it will work, you don't need to use all suggestions ass written above.
