I just bought a brand new Samsung TV model number QN75Q60BAFXZA.

Every time I try to open the apps menu to download apps I get the message, "The server is under maintenance. Please try again later. (400)"

I have reset the router, TV, and smart hub several times each.

My TV's current software version is 1622, T-NKLBAKUC-1622.5, BT-S.

Do I need to return the TV for a new one or is there a fix for this issue?
