Some powwow have problems unless on wifi.. One of my friends did as well until I rooted and installed Xnote 14 Rom. . Mine and my daughter's has always worked... All versions
This is what I did to fix connection error. Download/reinstall. Once done installing, do not open the app. You have to connect to a wifi. (a must) Upon connecting to wifi open the showbox app. That should fix the issue.
