Hi Nivethaa, what error messages did you get? What versions of Linux, MySQL, etc are you running? Did you follow the instructions near the top of the post about converting from PKCS #8 format (OpenSSL’s default) to PKCS #1 format (which is what MySQL expects)? Symlinking is unlikely to work as the certificate format will not match. You probably need to use a Let’s Encrypt post hook to automatically convert the certificate every time it is updated.
