What Is Causing the “Invalid Request, Authentication Expired” Issue on YouTube?

Why does YouTube say invalid request authentication expired? First of all, before we go through the workable solutions, we should know some possible reasons to cause this particular error:

Account timeout

This usually happens when the video takes a long time to upload. Your account will time out and you will automatically be logged out if you remain idle for a long time. If this scenario is applicable, you could try clicking the Refresh button on your browser. Then, you should be able to log in again and you are allowed to complete the process of publishing the video.

User logged into another account while uploading the video

Another common reason that is known to cause this particular problem is if you open another TAB or another browser and then log out of YouTube & into a different YouTube account.

An extension is causing the problem

Download Helper and Down ThemAll are two extensions that are known to cause this particular error on both Chrome and Firefox. In this case, the solution is to either disable or uninstall the extension from the browser.

YouTube account is unverified

There were some confirmed instances where the process of uploading the video was only successful after the account has been verified with a phone number.

Invalid Request, Authentication Expired FAQ

What does invalid request mean?
When an error occurs in processing a request received from the browser, the web server returns the 4xx HTTP status code. If the web server cannot handle the request from the client browser, it will send 400 Bad or Invalid Request HTTP response. This is usually due to the request's invalid syntax.
What does it mean when YouTube says invalid response received?
That means YouTube is blocking your IP address for some reason. You can't access YouTube until you change your IP address by changing your network.
What does invalid response from server mean?
The 502 Bad Gateway error is an HTTP status code, which means that one server on the Internet received an invalid response from another server. The 502 Bad Gateway error is completely independent of your specific setup, which means you can see it on any browser, any operating system, and any device.
How long of a video can you post on YouTube?
By default, YouTube allows up to 15 minutes of videos to be uploaded. If you try to upload more than 15 minutes of video, the upload will fail. This is YouTube's limitation, not a Brightcove's limitation.
