The title basically says it all. The subtitles don’t show up when serving them from a BunnyCDN location while using URL tokens.
When serving the same VTT file from a different location the subtitles display fine.

Hello Marc,
please send over your VTT file. I was not able to reproduce this issue. The Stream Loader does adjust the VTT file if it contains the sprite image references only.
Thanks,
Martin
This is not about the preview images Martin. It’s about regular text subtitles :)
Hello Marc,
yes, exactly. And according to my tests the VTT subtitles are not affected by the new Stream Loader technology which we put together. So I’m not sure why it’s not working for you.
Please end over your VTT file you are using, or even better a link to the page where we can see the issue.
Thanks,
Martin
Sure.
This subtitle file (https://mediacloud-tribe.b-cdn.net/2020/10/000_outro.vtt) doesn’t use tokens and works just fine in the play.
This file (https://coursevideos.b-cdn.net/cjme/outro/000_outro.vtt) does use tokens and doesn’t work.
Just to be clear I’m not sure if the tokens are the problem. But one location works and the other doesnt.
Hello Marc,
I don’t see why it wouldn’t work if it worked before.
Please, also try to open your browser developer console (here’s how https://kb.mailster.co/how-can-i-open-the-browsers-console/), then try to load the page with the video again and play it. See if any error appears on the console.
There should be a red notice with the subtitle VTT URL in it along with some error message. Otherwise you will have to open the Network tab of the developer tools, reload the page and play video again and see if the subtitles URL request goes out properly and what does it return.
Thanks,
Martin
Found it! Was a CORS error. Needed to add .vtt to the list.
Which is surprising because the VTT that holds the preview images on the same location was loading just fine.
Hello Marc,
the VTT with preview images loads fine as the Stream Loader feature of FV Player Pro removes the CORS requirement – it loads from the same domain as your website.
BunnyCDN should use a better default list of file extensions for CORS.
Thanks,
Martin
Their list of default CORS list is… blank :)
Maybe you can add this to your guide on enabling subtitles in case someone else runs into it.
Thanks for the help.
