oauth2 deadline exceeded errors?

[Paul Ceccato]

I'm using the excellent simpleauth module to manage authentication on my app engine application, it works perfectly for facebook, twitter and yahoo logins, and used to work fine for google as well.

The trouble is google oauth2 authentication seems to be broken for me over the last few weeks. I get these exceptions:

DeadlineExceededError: Deadline exceeded while waiting for HTTP response from URL: https://accounts.google.com/o/oauth2/token

Even the simpleauth demo app is throwing this error for me:

http://simpleauth.appengine.com

I was hoping it was an temporary glitch, but it seems to be ongoing for me. Very dissappointing, I would hate to be relying on this authentication service for a commercial application.

Does anyone know what gives? Or how I can resolve this?

regards

Paul

Hello Paul,

Occasionally Google authorization experiences some issues, but it certainly shouldn't be having trouble for that long. You probably have a different problem. First off, are you using a single account for testing? Can you try using another Google account for testing purposes? Also, are you logged into multiple Google accounts simultaneously? If so, log out of all of them before logging into one. 

In addition, can you provide a more detailed stack trace for your error?

Hi,

Sorry for the delayed repsonse...

The error happens with my account, and I am also getting numerous reports from my users about it so it is definitely not limited to my account. I am currently advising them to use twitter or facebook to authenticate with my application instead as their authentication mechanisms seem to be much more reliable and robust than google at the moment.

The issue has been intermittently ongoing for at least three weeks now.

Here is a stack trace from today, the exception is thrown long before the 60 second url fetch timeout occurs:

unhandled exception

Are you setting an explicit urlfetch timeout or letting simpleauth use the default timeout? If you're using the default timeout, try explicitly setting a long timeout with socket.setdefaulttimeout() during init (or at the beginning of handling the incoming request). Also, what happens if you upload a Google signin sample application ( https://developers.google.com/+/photohunt/python ) and attempt to authenticate in? Does the same issue occur?

And if nothing else works, file a production issue on the App Engine tracker: https://code.google.com/p/googleappengine/issues/entry?template=Production%20issue
