Error Embedding Player into WIX Website

I am trying to embed the kaltura player into a wix website using the iframe addon or the html extension addon but I always get the following error

{“severity”:2,“category”:6,“code”:6001,“data”:[],“handled”:false}

instead of the video or playlist that I would like to add. There is no access control and I tried using HTTP or HTTPS but I always get the same error code.

Any help on this?

Thanks!
