Using cPanel/Sectigo as the SSL provider for AutoSSL, you may occasionally get error :
The “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/. This can be fixed using 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 {} \;
Re-run AutoSSL for the and this should be fixed.
