generating a private key from a certificate for ISE portal certificate

[SMD28316]

I have a Public certificate that I would like to use for portal access, I followed the commands on this document to generate a private key from it:

https://www.digitalocean.com/community/tutorials/openssl-essentials-working-with-ssl-certificates-private-keys-and-csrs

But I'm unable to import it to ISE, as it keeps complaining about the private key not being correct, what should I do?

It's very likely that something went wrong. Did you go through the steps

Verify a Private Key Matches a Certificate and CSR

to check if private key and certificate matches?

Unclear exactly how you generated the private key and CSR sent it to Digital Ocean for signing into a public certificate. You also did not include the actual error text about the private key not being correct so there are no hints about the actual error or problem.  Please see How to Ask The Community for Help for your future requests.
