After you uploaded the SSL certificate, you receive the message "Invalid certificate, possible wrong password" on the portal.
Here are some tips for troubleshooting this error:
Check for problems with the certificate. Install it on your local computer. If you don't experience any issues then the certificate is good.
Ensure that the password does not contain any special characters. For testing, the password should only contain the characters 0-9, A-Z, and a-z.
If the certificate was created with Microsoft Software Key Storage Provider, the RSA algorithm must be used.
