Invalid Credentials

Ubuntu 11.04 x86_64 GNU/Linux
... same problem for me.

Ubuntu 11.04 i686 GNU/Linux

Likewise. And yes, imap is enabled and working, since I use it in Thunderbird on multiple computers.

interesting... Currently I don't remember any platform specific code in gm-notify, so if this problem really exists, it must have it's source in the underlying libs.

Could you please activate the debug mode by setting
_DEBUG = True
in line 28 of file /usr/lib/python2.*/dist-packages/gtalk.py and post the output of gm-notify running in a terminal?

Thank you!

Think this is the same problem: I cannot log in anymore since using Ubuntu 11.04.

This is probably a problem with my latest password change. I tried to enter the new one, but all "Invalid Credentials" was the answer. Is there a problem with the password field? My password is considerably longer than 20 signs and contains several special characters including spaces etc. Can this be a problem?

I don't know why, but suddenly it works again on both my computers.

I'm getting the same problem with my google apps account. If I enter the full username ( including @domain) and password it claims I have entered 'Invalid credentials'. Interestingly, it works for my other gmails (not google apps) account, which has the same password.

Let me know if I can produce any useful output.

My problem turned out not to be a bug - I needed to enable google chat for my domain before it would allow me to log in.

I installed this on Arch Linux yesterday and have this bug. Is there no way to troubleshoot this?

I have unlocked the captcha, made sure Imap is enabled, checked with different google accounts and re-compiled the app, and there don't seem to be any more suggested advice.

Could this have anything to do with 2 step verification?

I'm also experiencing this problem on Xubuntu 12.04 :(

here is my raw debug output

Sign-in attempt prevented
Someone just tried to sign in to your Google Account from an app that doesn't meet modern security standards.
We strongly recommend that you use a secure app, like Gmail, to access your account. All apps made by Google meet these security standards. Using a less secure app, on the other hand, could leave your account vulnerable.

To use GM-Notify you have to activate "less-secure Apps" through this link:
