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.test.schulcloud-thueringen.de 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 !
