Hello @Blockchain_Game_dev,

Could you please fill in the required info at the end of the template, indicating your project’s name, technology, etc? It’ll help us helping you.

Also, can you please check if you have any of these packages in your dependencies:

- [@google/maps](https://community.forestadmin.com/t/problems-authenticating-when-upgrading-to-v7-of-liana-forest-express-mongoose/2681/9)
- [google-auth-library](https://community.forestadmin.com/t/upgrade-to-forest-express-mongoose-7-x-x-failed-due-to-openid-login-callback/2569/7)
- [signalfx-tracing](https://community.forestadmin.com/t/unable-to-register-the-client-unexpected-error-connect-econnrefused-127-0-0-1-443/2813/4)

It seems that these libraries (or at least old versions of them) are making strange things with http code, and it conflicts with our calls.

Hi, i am using @google/maps but can’t I use google maps and forest admin at the same time even for testing on my local ?

It seems that this library is deprecated in favor of ` @googlemaps/google-maps-services-js` which does not have the issue.

</div>

Can you share a screenshot with the different calls happening during the authentication?

Do you have any call in error? Do you have any error in the console?

Also, did you follow all the steps described in the [documentation to upgrade to V7](https://docs.forestadmin.com/documentation/how-tos/maintain/upgrade-notes-sql-mongodb/upgrade-to-v7)?

I have no error in agent.

Agent logs :  
OPTIONS /forest/authentication 204 0.388 ms - 0  
POST /forest/authentication 200 2.052 ms - 1020

These are calls for authentication in network tabs.

I did all the steps except Running up multiple server instances because i am testing my project on my server.

Do you have any indication of a CORS error regarding the `POST`? It seems that it shows only provisional headers, which may indicate that there is a problem with CORS.

Ok, then there is a problem with the CORS configuration of your agent. Can you copy/paste the code related to CORS?

Can you please use the same config we can find in the docs?

It seems that there is still an error, as your POST request is not sent. But can you please make a screenshot of the list of all calls, not the details of these 3 calls please? I’d like to see how they are chained.

Please deactivate your extension to unblock CORS requests because we need to fix these cors issues.
