First, the error reports "change your network and retry", then you should check whether your access to internet is normal. If your internet is not decent, please improve your internet connection. Besides, check whether you have installed Firewall on your phone, and turn it off if it's on. Second, the error reports "invalid key", which means the API Key is invalid or it has expired. Doublecheck and make sure that the API key you imput or scanned is authentic. Moreover, recreate a new one If it has expired.
It's probably because your API key doesn't permit "enable trading" or has expired, or you don't have enough balance on exchange. （1）If you didn't select "enable trading" when you create API key, you should go to check that permission. （2）If your API key has expired, create a new one please. （3）If you don't have enough balance on your exchange account, go to deposit more.
BitUniverse does not charge any trading or other hidden fees, and simply has no technical way of doing that. We advise that you not allow "withdraw funds" permission of your API Key, so that you are restricting direct access to your funds on exchange.
