I’m not sure why you are sharing Apigee docs, Singin with Google only requires a Google Cloud account with oAuth credentials, especially if user management is done externally (Which it is). ref
I’m also a little confused as to what point you are trying to make, oAuth tokens do timout, Google has that set to 1 hour (Or at least they did at some point, I can’t find an official source atm)
And for the public, I went through several repositories to get things to work, then mixed matched the files between environments in the way later morning.
I’m saying the Euro-trash experience is seemingly enabled by an emotionally disturbed person in The Netherlands. Does that answer both of your questions?
Closing as this is off topic. Admin has enough information to fix this, or will ask you privately for more. Do not attempt to continue this discussion.
The topic is now closed because you seem to be more concerned with personal attacks than actually having a productive discussion to resolve this issue. I don’t understand why the conversation went into this direction, just because there was some disagreement about some peripheral implementation details.
As for the issue itself, the HAR file is very helpful. The third request in the list is the thing that actually makes the OAuth link work. You make a request to the /profile/manage-social-login endpoint, and get a response with a 302 status code, indicating a redirect. The actual redirect URL there is pointing to https://accounts.google/o/auth2/auth, which is the Google login endpoint.
All the request times here look very normal to me. So if it’s loading for a long time, then my best guess is that your browser is having trouble loading the Google login page. Because the HAR file shows that everything on our end is working as intended, and not slow by any means.
