Invalid Server autentification Kobocollect

I have done all recommendations posted on older questions and responses, but still I receive the message the server requires authentication. Please what can I do? I want to upload the forms made on kf.kobotoolbox on the application Kobocollect.

Welcome to the community, @jsfeiner! Could you also share a screenshot of the error message you are getting? If I understood you correctly, you seem to be trying to connect your Collect Android App with your account to get the blank forms. Is that what you are trying to do?
