403 No Compatible Creatives

I'm receiving this error:

error playing ad/video: {"code":403,"message":"No Compatible Creatives"}

But when I click the ad tag that it is getting, I see the "Creative" (video link) in the VAST response.

What exactly does this error mean?

What kind of creative is sent in the response? If it is a Flash .swf, you need to make sure our player is in Flash mode first. Add primary: ‘flash’ to your jwplayer().setup() if it is not there already.

Hello I have the same problem I have tried in two primaries but no one helps me, any other idea?

Please post your ad tags here. You can also test your ad tags in our Ads Tester at
You may need to change the player’s mode to Flash or HTML5 for your ad to work. You may also need to test with both VAST and Googima clients.
