What is causing the ‘Invalid Request, authentification expired’ issue?
We investigated this particular error message by looking at various user reports and the repair strategies that are commonly used to resolve this particular issue. From what we gathered, there are several common scenarios that are known to cause this particular error:
Method 1: Refreshing the page
If the video took a long time to upload on Youtube’s servers, chances are you were logged out (or timed out) due to inactivity. If this is true, you will need to refresh your browser and log in again to get rid of the error message. After you reinsert your credentials and log back into your Youtube account, return to the page that was previously showing the ‘Invalid Request, authentification expired’ error and see if you are now able to make the video Public in order to publish it. If you’re still encountering the same error message when trying to publish, move down to the next method below.
Method 2: Don’t log into a different Youtube account while uploading
As several users have reported, this particular issue can also occur if you have logged into a different Google account from the same computer while the video was being uploaded. Although we haven’t been able to find an official explanation on this issue, users speculate that this behavior is probably a Youtube security mechanism to protect against abuse. As you can expect, the solution is quite simple in this case. You’ll need to re-upload the video again and make sure that you’re not logging into a different Google account while the uploading of the video is in progress. Note: Keep in mind that logging into a different Youtube account from an incognito tab or a different browser will produce the same error since Google will still see the same IP. If this method didn’t resolve the issue or it wasn’t applicable, move down to the next method below.
