Hello @user1, Thank you for your message. If I understood well, you upgraded your `forest-express-sequelize` from version 2 to 8? Did you follow the upgrade [notes](https://docs.forestadmin.com/documentation/how-tos/maintain/upgrade-notes-sql-mongodb)? Thanks. ---

Hey @user1, Thanks for searching all those information. We will try to find the culprit. 🙏 The network indicates a failing calls on the **/forest/authentication/callback** URL. - Do you encounter the issue on _development environment_ or on _production environment_ ? (I don’t find any _pgsl_ environment for the project rental-admin) - Can you share your **APPLICATION\_URL** environment variable ? (It can cause this issue) Thanks in advance. Kind regards, Morgan ---

Hi, I can’t check the environment from [https://app.forestadmin.com/projects](https://app.forestadmin.com/projects) , I don’t know why. Is there any other way to check it? ---

Ok, you can see it on the upper-left corner of the application when you join a project but lets forget about that. I need to know your **APPLICATION\_URL** configuration. 🙏 > [@morganperre](#): > > - Can you share your **APPLICATION\_URL** environment variable ? (It can cause this issue) Regarding the configuration of the **rental-admin** project, for **your production** , it should be to ```javascript APPLICATION_URL=https://rentaladmin.wildtangent.com ``` Let me know if this helps. Kind regards, Morgan ---

Hi again, **APPLICATION\_URL** environment variable so it can be most of the time in a `.env` for localhost config (development). In production config it can be store on a specific way depending on your host services (AWS, Heroku, GoogleCloud, Azure, …) Can you ask a colleague for this information ? Regards, Morgan
