Marcelo Giorgi 4 years ago In our site, we are using the JS API to track the events, for that we use the library froogaloop. We have a couple of domains that points to the same site. And from time to time, not always, We receive a warning message that prohibits froogaloop to register the 'ready' event, which we use to register for the other events, such as: play, pause, etc. The warning message looks like this: "Unable to post message to http://. Recipient has origin ." You can also see it in action, here: postimage.org/image/k2ccg1fjj/ This looks like a bug, because it happens occasionally, but please let me know if it is not and there is a workaround it. Thank you!
