Hi @schoen .
I am hosting provider .
How fix this Error ?
[root@host ~]# wget -qq -O - https://cpanel.fleetssl.com/static/generate_support_data.sh|bash
FATA[0004] Self-test failed
Redirecting to /bin/systemctl status letsencrypt-cpanel.service
Please provide this string to support: 492e85e4-b901-40e4-a68a-d6ed23f45261
"Let's Encrypt for cPanel" is the former name of a specific commercial product, which was renamed to FleetSSL because the original name was potentially confusing. This message does not mean that Let's Encrypt no longer works with cPanel, but it means that your host's particular copy of the FleetSSL software is not working. You should then follow the request to contact your hosting provider's support.
If you are the hosting provider, as in @clack's case, you should contact FleetSSL support via
