    Hello Abhishek,

    You will need to provide the host as your Public IP address. Your home router must also allow port forwarding (port 5432) to communicate.

    It looks like you have provided a private IP address (192.168.56.1).

    To get your public IP you can go to the following link:

    If this is helpful please accept answer.

    @Abhishek Patil Thanks for reaching out.

    You need to Ensure that your PostgreSQL database is accessible from the internet. You need to ensure that your PostgreSQL database is accessible from the internet by configuring your router to forward incoming traffic on the PostgreSQL port (default port is 5432) to your laptop's IP address. Make sure to have the static IP as if you have dynamic IP then the connection IP would be changed every time.

    Once you have verified the above step then you need to Configure your PostgreSQL database to allow incoming connections: You need to configure your PostgreSQL database to allow incoming connections from the internet. You can do this by modifying the pg_hba.conf file to allow incoming connections from your Azure Function's IP address

    If you need any assistance on the above then I will suggest you to reach out to the postgres database for the configuration help or someone from your networking team that can help you with the setup so your DB can be accessed over internet.
