Thank you for reaching out to JW Player support. Sorry to hear your video is no longer working. What stands out to me here is the change from HTTP→HTTPS. Have you implemented a crossdmain.xml file at all during the implementation. This allows successful queries from cross domains and can sometimes cause slight problems with setups, heres a really handy link that gives more information on this http://support.jwplayer.com/customer/portal/articles/1403679-crossdomain-file-loading . Another thing we may want to look at is the actual HTTP request in your code, are all of your HTTP requests now modified to HTTPS requests? Feel free to send a sample code over to use so we can take a look.
