Virtual Tour (360)

Hello, I need you to guide me because I have not been able to solve the issue, I have investigated in documents and not found the answer, I am working on localhost, to present content, I have all the h5p plugins that I found installed in moodle, and when I do the activity and I try to call it to show it, I get this error, can someone tell me what happens? I would like to generate content without using the iframe of h5p.org but something more native to the platform, is there any way or it depends on the server and iframes external, thank you!

Hi, 

I just added an Youtube video in a Virtual Tour scene usig the scene editor. In Accessibility tab > Add video track with Subtitles kind selected, I set srclang to to ro (from romanian) and I uploaded a standard .vtt file.  However, the translation is not showing.

Can you help me ?

Thank you !
