Google App Engine says "Must authenticate first." while trying to deploy any app

Google App Engine says "Must authenticate first." while trying to deploy any app:

me@myhost /opt/google_appengine $ python appcfg.py update ~/sda2/workspace/lyapapam/

Application: lyapapam; version: 1.
Server: appengine.google.com.
Scanning files on local disk.

Error 401: --- begin server output ---
Must authenticate first.
--- end server output ---

We are getting this message with any application and under any developer account available to us

That's what we have installed:

Python - 2.5.5         App Engine SDK - 1.3.2
PIL    - 1.1.7         ssl            - 1.15

How can I fix it? Is it well known problem?

Update:

开发者_如何学运维I really had a problems with time synchronization immediately after installing Windows on the same computer where I have Gentoo installed, but I've fixed that soon by setting RealTimeIsUniversal in registry and setting synchronization with europe.pool.ntp.org in both systems. (BTW my time zone is EEST)

A couple of days after I solved a problem with time synchronization appcfg.py asked me for a password after each line it printed out (that was really weird) and I've used --passin and unix 'yes '.

Now I have this problem with "Must authenticate first." and I've spent a lot of time playing with --passin --insecure --no_cookies options in different combinations on both windows and linux without any success.

it is very likely that, say you have account(s) that are in good standing, that the clock on your system is set incorrectly. this causes such authentication failures that you got.

here's a related post from last summer outlining this exact problem (and solution): http://groups.google.com/group/google-appengine-python/browse_thread/thread/a57fc866838b0b32

if your clock is correct, and you think you may have other issues, reach out to the Google App Engine developer forum for assistance: http://groups.google.com/group/google-appengine-python

It should prompt for your user and password. Are you running this from a script?

If so, you can use the option: --passin

If given, the tool accepts the Google account password in stdin instead of prompting for it interactively. This allows you to invoke the tool from a script without putting your password on the command line.

This is also the same error message displayed some times when your password has special characters in it, like a $.
