The Let's Encrypt HTTP challenge failed: acme error 'urn:acme:error:unauthorized': Invalid response from
If you see this when trying to add a Let's Encrypt SSL for your domain there are a few possible reasons:
1. Permissions for the required directories have been changed. To check this login VIA ftp or File Manager and in your public_html directory make sure that /.well-known and ./well-known/acme-challenge both have 755 as permissions.
2. There is something that is messing with URL structure in your root directory. The most common cause of this is the .htaccess file. Try renaming the .htaccess file something like off.htaccess and try assigning the Let's Encrypt SSL to your domain again.
These 2 things account for 9/10 issues encountered with the Let's Encrypt in your cpanel account. If you have checked both of these but continue to have issues please don't hesitate to contact our fanatical support!
