Error code 103 I cant log in please help

Hello

When I start the game Knights and Dragons a notification pops up with error code 3 and the game cannot start up. (The Error 3 also states if I complete the tutorial I can get gems, this is strange because I already completed the tutorial.)

Also i did the following things:

- I got the latest version of Knights and dragons (no update in the google play store).
- I removed and installed the Knights and dragon apps several times
- I tried different Wifi connections to connect to but still got error code 3
- The Wife connections works because I can go to other websites and download the app again
- I also tried to change the date and time (this was a solution I read on internet forum but it also did not work)
- I put my tablet back to the factory settings and installed the knights and dragons app.

This problem I have now since Wednesday evening. And I can?t fight the boss for legendary armor and compete in the Arena tournament

Your help is much appreciated

Grtz
