Thank you for the post!
When it comes to a "BadParameter" error message, when you import a certificate, you need to ensure that the key is included in the file. If you have a private key stored separately in a different format, you need to combine the key with the certificate. Some certificate authorities (CAs) provide certificates in other formats. Therefore, before you import the certificate, make sure that it's in either PEM or PFX file format and that the key uses either Rivest–Shamir–Adleman (RSA) or elliptic-curve cryptography (ECC) encryption.
If you're still running into issues, can you please provide what documentation you're following when creating/uploading your certificate. I was able to find some docs which walks through the process, which I'll post below.
I hope this helps, if you have any other questions please let me know.
Thank you for your time and patience throughout this issue.
