Please fill out the fields below so we can help you better. Note: you must provide your domain name to get help. Domain names for issued certificates are all made public in Certificate Transparency logs (e.g. https://crt.sh/?q=example.com), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.
My domain is: broadstairsmotcentre.co.uk, which is mapped to http://broadstairsmotcentre.boschauto.co.uk/
I ran this command: Plesk - Add Domain to mapped Domain - No issue with other domains
It produced this output:
Error: Could not issue a Let’s Encrypt SSL/TLS certificate for boschcentre.co.uk. Authorization for the domain failed.
