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.
This means that somebody has probably been manually issuing certificates using a website like zerossl.com or gethttpsforfree.com and installing it using cPanel. There is no easy way to do autorenewal with cPanel if AutoSSL is disabled on the cPanel service, which appears to be the case with your server.
You should talk to whoever set your certificates up in the first place, or talk to your web host. If you can’t do that, then try use one of the above websites to issue a new certificate.
