CAA DNS records: control which CAs can issue your SSL
Understand CAA DNS records, check whether one blocks AutoSSL or your paid CA, and add correct CAA records in the cPanel Zone Editor without breaking renewals.
Check which SSL certificate is installed and when it expires
Verify an SSL certificate: view issuer, covered names and expiry in the browser, cPanel SSL/TLS Status and the command line, and test the full chain externally.
Fix an expired SSL certificate and renew it in time
Recover from an expired SSL certificate: find out why AutoSSL did not renew, re-run it, renew and reinstall a paid certificate and set up expiry monitoring.
Fix an incomplete SSL certificate chain (missing CA bundle)
Fix "incomplete chain" and untrusted certificate errors on phones and apps by installing the correct intermediate CA bundle in cPanel, WHM, Plesk or DirectAdmin.
Fix common SSL errors in the browser
Understand and fix common browser SSL errors: name mismatch, expired or untrusted certificates, incomplete chains, protocol errors and HTTPS redirect loops.
Fix SSL certificate warnings in email clients
Stop certificate warnings in Outlook, Apple Mail and phones: use the correct mail server name, check AutoSSL covers mail subdomains, and pick the right ports and encryption.
Install a paid SSL certificate in DirectAdmin
Install a commercial SSL certificate in DirectAdmin: create the key and CSR, paste the certificate and CA root bundle, enable SSL for the domain and force HTTPS.
Install a paid SSL certificate in Plesk
Install a purchased SSL certificate in Plesk: create a CSR, upload the certificate and CA bundle, assign it to the domain and redirect visitors to HTTPS.
Install an SSL certificate on a domain in WHM
Install a paid SSL certificate for any account's domain from WHM: paste the certificate, private key and CA bundle, use autofill and verify the chain afterwards.
Manage service SSL certificates in WHM (Exim, Dovecot, FTP)
Use WHM's Manage Service SSL Certificates to see and assign the certificates used by cPanel, Exim, Dovecot and FTP, reset them to default and fix mail client warnings.
Self-signed SSL certificates in cPanel: when and how to use them
Understand self-signed SSL certificates in cPanel: why browsers warn about them, when they are acceptable, how to generate one and how to replace it with a trusted AutoSSL certificate.
SSL certificate types explained: DV, OV, EV, wildcard and multi-domain
Understand SSL certificate types: domain validated, organisation validated and extended validation, plus wildcard and multi-domain (SAN) certificates and when to use each.
