Theme update – key not accepted

I have followed the instructions and created an Envato private key. However, when entering the key into the Enfold update page, I still get the below messge. Can you help me figure out what I need to do?

Last time we checked the token we were not able to connected to Envato:

Purchases could not be accessed
Username could not be accessed (needed for your information only)
E-Mail could not be accessed (needed for your information only)

Following errors occured:
