Color Laser Jet Pro MFP M477

I own a HP Color Laser Jet Pro MFP M477 and recently changed my Wi-fi, since doing this I am no longer able to scan to email, the following error message appears:

Username or password is incorrect. Ensure both user account and password are valid.

I don't remember setting up a username or password so I can only assume this is related to the new Wi-fi. 

Please help?
