2.15.1.2.3. Specified key does not match certificate

When installing a certificate, you may encounter the error "The specified key is not suitable for the certificate".

Please try the following:

1. Open the certificate and private key files in any text editor.
2. Check for empty lines between lines that start with -----BEGIN and -----END and lines that contain certificate and key data. If empty lines are present, delete them and save your changes.
3. Try installing the certificate again.

If there are no empty lines in the files but the error still occurs, contact your certificate provider to find out the possible causes of the problem.
