Embedded Subtitles stopped to show on Chromecast

[DrigoRJ 0]

Hi, I was using Emby installed on a Docker container and was working flawless on a Chromecast. But someday it didn't show anymore subtitles of files with embedded subtitles.

If it is a external file, like .srt, it shows normally but embedded subtitles no. I already deleted its container on Docker and recreate but it didn't work.

Could you help me?

Some infos may help:

We use android phones to cast for Chromecast

Emby version is 4.7.14.0

One of the files with subtitles:
