When using cPanel/Sectigo as the SSL provider for AutoSSL, you may occasionally see this error in the autossl log:

The “cPanel (powered by Sectigo)” provider cannot currently accept incoming requests. The system will try again later.

This error seems to be caused be incorrect permissions in /var/cpanel/ssl/domain_tls/. You can fix this with the following command:

find /var/cpanel/ssl/domain_tls/ -mindepth 1 -maxdepth 1 -name .pending_delete -prune -o -type d -not -perm 755 -exec chmod -v 755 {} \

You should then re-run AutoSSL for the user(s) in question.
