I am using same JWplayer key for both localhost and the server. It is working absolutely fine in the local. But on the server side I am getting the following error.
Jw player missing license key
Please correct me if I am asking anything wrong
It's hard to answer this without seeing your embed code, but you if you are self-hosting our player, you need to define jwplayer.key after you load the player library but before you call jwplayer().setup().
