Bugs in content types

Hi. I realize this issue has been raised in other posts, but I can't find anything that addresses my particular case. I'm working on what I think will eventually be a fairly large library of interactive videos, and I think we are going to host the videos themselves on our own domain, simply to ensure control over the content. (I did do a test run using YouTube, but the pop-ups when embedded videos are paused made it imptactical; that's the kind of issue we're aiming to avoid.)

Hi, guys, I'm working on h5p-8.x-1.0-rc13 installed in Drupal 8.6.10,I could not install new content types when I tried to add new content-->basic page. The error code was Failed to download the requested H5P. cURL error 28: Operation timed out after 30015 milliseconds with 261695 out of 1015458 bytes received And it seems no one encounted this question. How to fix it? Thanks!
