"Unable to cast" - MKV files with subtitles

I recently started seeing this issue. When I cast MKV files, I'm getting "unable to cast".

Here's some snippets from the server log

I think this is related to the subtitles in my MKV files. It's weird that this suddenly started happening recently. I'll post the whole server log as well.

My server is running Centos 7. I'm using the latest generation chromecast.

    Did you get any help with this?

    Mine plays fine from the plex app on my phone to chromecast. But not from chrome browser to the same chromecast.

    Still seeing this issue on PMS 1.5.3.

    I also have issues playing video from my laptop. I've made a post about it here, thinking it was a separate issue, but I think its related.
