HELP ERRORS

Best regards, we generated a new ticket since the previous two were cancelled, in the attached file we can find the problem we have, we have the web page above as we show in the url that we attached below this message, the system shows us a error 400 and 300 we do not know what else to do to correct we have tried everything, we have a question why it shows us a different page than the one they have on the portal where we bought the code, how do we get it to show us the same, We also want to know, then when installing the Flutter code, is it uploaded for Android TV, can it be uploaded for Android cell phones? Please explain to us how the project works since looking at all the documentation we see that it has a website and an Android TV app but it does not allow us to see the movies that we attached from the panel in the pdf file. We explain our problem in detail. We attach credentials and the url from where We have everything set up, please help us urgently
