Failed to authenticate

[matejaputic]

Failed to authenticate even though I can authenticate through the website. I made sure I have accepted the honor policy for the course, but the behavior is the same. Also tried changing my password to a shorter password, that didn't help either. I believe I am using the latest version. Is this just a never ending cat-and-mouse game with Coursera? Any help would be appreciated.

Same here, unable to download anything. Seems like they changed their login behavior very recently.

This is probably because coursera changed something on their authentication side. So the coursera-dl code needs updating. Has happened a couple of times before and usually not major. I will take a look but don't have much bandwidth, so it wont be this week. So anybody able to already take a poke at the code would be much appreciated.

The error is Invalid CSRF Token

[HyShai]

You can see the change needed to implement here - basically it needs another CSRF token.

(I don't have time ATM to do it here)

Oddly enough, the 2.0.2 version authenticated correctly for me. Downgrading might be a plausible workaround until the issue is resolved.

$ pip uninstall coursera-dl
$ pip install coursera-dl==2.0.2

[HyShai]

Can confirm 2.0.2 authenticates.

Thanks @Jared314

[nick-s-b]

Are there any issues with 2.0.2 branch?

[visini]

2.0.2 worked for me, thanks!

[danmbox]

Where was 2.0.2 in Git? I don't see any tags...

[nomoreidsavailable]

Confirmed! 2.0.2 worked for me as well! Thank you!

[ghost]

2.0.2 Works well Thanks Jared314

I've tried commit ac0c411a69ebea3ffb26944b23c5a92718921007 on the mechanize branch (which seems to be version 2.0.2) but I'm still getting authentication problems

[beastman001]

Downloading epidemics-002 with Version 2.0.2. Works, but some 0 byte files.

[danmbox]

beastman001 -- well, it's on the requests branch that used to have problems and was eventually abandoned. That's why we need to fix the mechanize branch

[danmbox]

OK, for some reason ca9d3b35777534774a9777ad0fbc32e8b699da3d (2.0.2 on master) works, but ac0c411a69ebea3ffb26944b23c5a92718921007 (2.0.2 on the mechanize branch) doesn't. There's an extra 'csrftoken:' header, but even if I add that, it still doesn't work. The actual failure is that the second request returns a "400 Bad Request" error (which is not caught immediately).

[danmbox]

I've created a pull request for mechanize (#166). Seems to solve the issue.
