Installation and server related problems

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!

Moodle 3.9.6+

Hi, I'm not sure if anyone can help with this but I seem to have an issue with H5P interactive content activity not loading in Moodle. 

I think it is related to something server/DB side rather than the plugin itself but would be grateful if anyone has any advice. I have noticed that TinyMCE editor on Moodle Label activity doesn't load either so I feel it is related to js not loading. 

From the error console in chrome I get the following:

7d64da4609009d87511b2329e2f8ae02648b25aa.css:1 Failed to load resource: net::ERR_HTTP2_PROTOCOL_ERROR

Hi!

I'd like to migrate my H5P content to another Wordpress website, unfortunetely it's a lot so I need to transfer it.

There doesn't appear the option to download a H5P-file from the content (see screenshot). So I can not do it one by one?

Is there any solution for that? I don't want to mess up my database and copy it from my SQL. That would only be my last option.
