Is there any good free ssl certificates I can use that will work with InfinityFree?

Follow this guide to get a GoGetSSL Unlimited Trial certificate:

Use https://freessl.space, but you need to generate a Private Key and CSR from the “SSL/TLS” section of the Control Panel for your domain compiling all the fields while generating the CSR, check “I do not want to use default parameters (CSR, Admin and Tech contacts)” and “I have your own CSR” and put the generated CSR in the field, compile all details, and select the Mail Method (it needs your domain to have the MX record set to mx.epizy.com and a mail account that is at least named admin@yourdomain) to verify your identity. After that you have to install the certificate, and you can do that without any problem by following these steps and copying only the certificate, not the CSR or the certificate chain. After 90 days, you can repeat the steps again.
