There have been numerous complaints of YouTubers receiving the “Invalid Request, authentification expired” message when attempting to upload a video or videos. When users try to share their videos with the world by making them accessible to the general public, they often run into trouble.
Method 1: Reloading the page
Youtube’s servers may have timed you out if the video took a long time to upload. If this is the case, try logging out and back in to get rid of the error notice.
When you connect back into your Youtube account, try publishing the video again; the “Invalid Request, authentification expired” problem message may have been caused by an expired session cookie.
