Your SSL Manager has a section to cut+paste the cert. However, the cert provider (LetsEncrypt in my case) has produced 3 files; one 0000_cert.pem, + two chain files 0000_chain.pem, and 0001_chain.pem; My guess is the chain files are the intermediate certs that lead back to the root, do these chains also need to be installed on your server, or will the cert only suffice? If it helps, the file contents are: The 0000_cert looks like it has 1 cert -----BEGIN CERTIFICATE----- etc -----END CERTIFICATE----- First 0000_chain has 1 cert: -----BEGIN CERTIFICATE----- etc -----END CERTIFICATE----- Second 0001_chain has 2 certs: -----BEGIN CERTIFICATE----- etc -----END CERTIFICATE----- -----BEGIN CERTIFICATE----- etc -----END CERTIFICATE-----
