When attempting to upload the Private Key ID in our Production account, we are encountering an error issue.
Reason and Solution :Currently, OpenSSH format for private keys are not supported. One can only use the PEM format.To resolve the error, one must convert the PrivateKey.ppk to a PEM format, and try the same steps from earlier. One should now be uploading a PrivateKey.pem file for Step 4. After saving, you should not encounter any errors and should be successfully able to create a New Private Key.
