Description of your issue, suggested solution and other information

Downloading exclusive videos on Vessel with username and password used to work a couple of days ago, and now I can only pass cookies. I believe a 7 or 10 day free trial for Vessel membership is available, or ask people watching LinusTechTips on Vessel. If neither is possible, email admin@nixiesubs.com for a valid credential. Please include the URL of this issue.

If you're ever going to fix this, the time is now, since the service is going down literally tomorrow. Lots of content is going to vanish very soon.

Since Vessel is going down (no pun intended), I'll close the issue myself.

Thank you for mentioning the --add-header workaround. I guess I'll spend some words on how to do that.

1. Log into vessel on your browser
2. HIt F12 or Ctrl-Shift-I to open the developer tools
3. Click on the Network tab
4. Refresh the Vessel webpage
5. Back to the network tab, scroll to the top and click on the first request
6. Look at the Cookie header and copy it. This is what it should look like:
7. At the prompt type youtube-dl --add-header ', then paste what you copied, then ' followed by a space and the url(s) of the videos you want to preserve.

Of course this still only gives you access to videos you have a right to watch. If you don't have a subscription, you probably can't get one now, so you're out of luck.
