400 error codes usually appear when an error occurs in the request that prevents our server from processing it.
The most probable causes are:
- The certificate has not been signed by a recognized authority.
- The type of certificate is not valid for the service you want to access.
- The certificate has expired.
In the event that you receive an error of this type (except errors 403 and 404), you can contact technical support by any of these means, indicating the error code that appears and the procedure you were trying to carry out.
