@gerardo_grimaldi I checked your account. for some reason the player you have is set with the flag “disableHLSOnJs”=true, meaning native playback of HLS over MSE is disabled.
The player name is “Player final FWTV”.
I don’t know why this was set up like this.
The setup can be viewed in your KMC account in the player studio.
The section containng this config is under the plugins section in the UI Variables section:
You can either delete it, as it’s default is “false” or set it to false.
Again, I’m not aware to why this has been done, so please practice with caution when altering your config.
