Won't upload YouTube vidoes

Hi, I’ve installed and started using the plugin. After uploading several videos (all went well) I then tried to upload some more and for the Youtube videos e.g. https://youtu.be/kesrfKZHlXo and I get an error message that it could not generate details!

Then I tried to upload the video from my pc and after waiting and waiting for over 20 min, I gave up.

What’s up, any suggestions?
