Why was my seller application rejected?

Hi there! I signed up for Amazon Seller Central with my LLC. I uploaded all the necessary documents, but I got rejected. Amazon won’t tell me what the problem was – therefore i hope you can give me some clues, as i don´t want to register again and get rejected a second time. I upoaded the “article of organization as proof of business” adress. Was that maybe wrong?

NOTE: Support told me they can’t see why i got rejected but asked me to try registering with a different phone number and email address again.
