can I get let's encrypt

Hi support
I need your help to install let’s encrypt to my cpanel
it’s free so please don’t see
let’s encrypt only for premium hosting

No, you can’t get Let’s Encrypt on free hosting. Bot access to websites is blocked on InfinityFree, so Let’s Encrypt cannot verify your domain name. This is not something which is easily fixed (except for turning off the security systems, which we’re definitely not going to do).

Premium hosting doesn’t have this security system and it has Let’s Encrypt integrated conveniently in cPanel.

so how can I get free ssl
I’ve private key and certificate key and csr but it’s not work

null
I put it on tls/ssl but doesn’t work
