Server returned an error: %s (Incorrect password?)

Error message

Server returned an error: %s (Incorrect password?)

What it means

Raised as AssertionError inside baidu_pan_protected_share (src/you_get/extractors/baidu.py:293). This function verifies the share password by POSTing to Baidu's verify endpoint; a nonzero errno in the JSON response means the password was rejected (or the verify request itself was malformed), so the code aborts with '(Incorrect password?)'.

Solutions

1. Double-check and re-enter the correct share password.
2. Confirm the password manually on pan.baidu.com in a browser for the same URL; if the browser also fails, the share/password pair is wrong.
3. If the password is right but it still fails, Baidu likely added extra verification — update baidu_pan_protected_share or upgrade you-get.

try:
    baidu_pan_download(url, password=pwd)
except AssertionError as e:
    if 'Incorrect password' in str(e):
        pwd = prompt_user_for_password(url)  # re-ask, never loop blindly
    else:
        raise

When it happens

Trigger: Calling baidu_pan_download on a password-protected pan.baidu.com share where the supplied password is wrong: the POST to the verify URL returns JSON with errno != 0. Also triggered when the verify endpoint response format changes and errno is nonzero/unexpected.

Common situations: Typo in the share password; stale password copied from an old post; Baidu adding extra captcha/verification the script cannot satisfy, surfacing as a nonzero errno.
