Downloading manifest fails, code 401

[Reimnop]

What did you expect to happen?

It's supposed to download successfully.

Instead of that, what actually happened?

It fails with the error: "Encountered 401 for depot manifest 440312 5480926750400450243. Aborting."

Which operating system are you running on?

Windows

Additional Information

The game I tried to use this on is Project Arrhythmia, specifically the latest manifest in its alpha branch. It was working last week, but now it breaks.

I also notice that #521 reports a similar issue, but I think mine might be a different case because I am not in China, and my friend who is in Russia also encounters the same issue, at around the same time, on the same game.

We haven't tested it on any other game.

The official Steam client works fine, which makes it really odd.

I successfully downloaded a previous version of another game from the beta branch using the steam download_depot console command last night, but a few hours later the same command returned access denied and still not working. I think it may be related to this problem.

I just tried DepotDownloader, got 401. Passed the name of the beta branch as an -beta argument, and it starts downloading. Looks like steam now checks beta branch.

Gonna close as the issue appears to be that -beta is required for manifests that were not in public branch.
