I'm using the login URL supplied by UserService.createLoginURL(...) as described in http://gae-login-explainer.appspot.com/#section_GAE_login.

The problem is that when one of my users encounters a reCaptcha, upon completion they are redirected to https://accounts.google.com/signin/lookup instead of back to my site.

The redirected link https://accounts.google.com/signin/lookup is a 404 page.

The relevant code in question is:


use google\appengine\api\users\UserService;

$url = UserService::createLoginURL($_SERVER['REQUEST_URI']);

$url is https://accounts.google.com/ServiceLogin?service=ah&passive=true&continue=https://appengine.google.com/_ah/conflogin%3Fcontinue%3Dhttps://*****.appspot.com/.

Is anyone else seeing the same thing? Is there anything I can try to change?

  • I've found that if a user logs out of Google, and then tries to log into my site - it works. I'm not sure in what causes Google to force users to enter a captcha, but when it does happen they are thrown into a 404. – Dave Chen Jun 5 '19 at 15:58
