Android can't connect to xibo server

Previously i can connect android to xibo server, Today my android hung and i try reset factory default. Now i try install xibo again on my android and setting ip cms and key but in display menu cannot logged in. I try schedule now, android not show image. please help me.

The most likely cause is that the factory reset caused a different licence key to be generated. You probably need to ensure your display is listed in the CMS (you may need to delete the old one if you have a limit to the number of display slots you are allowed) and also may need to update your license pool in the springsignage.com portal.

Thank’s for your reply, i cannot delete display “No integer match found for [] and return value is not an integer”

Does the display show as “Logged In” ?

Does the hardware key in the Player settings match the hardware key in the Display edit form?
