For the last few days I’ve been trying to embed a video into my website. I’ve tried using both Vimeo & YouTube for hosting, and ensured the links are correct (Youtube.com/watch_____), and still the errors of “failed to fetch” or “invalid URL” happen.
I’ve tried using both the Video and YouTube element, though despite the various methods/hosts it continues to fail.
I’ve not seen any issues, and just did an embed with no problem.
I suspect the most likely cause is that a browser extension is interfering. Try turning them all off, and see if the linking works. If it does not next step will be to clear your browser cache, but I suspect that will not be necessary.
I’ve seen similar problems with Chrome extensions breaking Google Drive uploads.
