Logic Pro X not letting me upload to soundcloud, keep getting “SoundCloud upload failed”

So I’ve become super frustrated with how I took a long break from music and as soon as I come back to it, now I can’t upload a finished project.. especially because I’ve tried and tried all day. I’ve reset my preferences, I’ve restarted my Mac, I’ve done so much, I even updated logic thinking that was the solution without a doubt. Once I saw the error message again, I felt completely hopeless honestly. I just found that I also haven’t had the newest software update, so that’s in process of downloading at the moment. I’m done getting my hopes up for today since nothing has worked, but I am wishing this update will resolve the problem. I’m sorry to sound so impatient and whiny but I’m completely dissapointed by now, which is why I even came to write this, so all I’m asking for is, if this update ends up not working at all as the solution, what other solutions are there or what could I do in general for this NIGHTMARE to end, thanks for the time.
