4XX error codes

400 error codes typically appear when an error occurs in the request, preventing our server from processing it.

The most likely causes are:

  • The certificate has not been signed by a recognized authority.
  • The certificate type is not valid for the service you want to access.
  • The certificate has expired.

If you receive an error of this type (except errors 403 and 404), you can contact technical support through any of these methods, indicating the error code that appears and the procedure you were trying to carry out.
