    This issue is tend around Nginx from what is see above trying to bind to specific IP addresses on port 443. This error typically occurs when the IP address you're trying to bind to isn't available on your local machine.

    Some few steps you can work with in troubleshooting and resolve this issue:

    1. Check IP Addresses: Ensure that the IP addresses 10.101.121.15 and 10.111.121.13 are correctly configured on your local machine. You can use the ifconfig or ip addr command to list all available IP addresses.

    2. Modify Nginx Configuration: If those IP addresses are not available, you might need to update your Nginx configuration file to use an available IP address or 0.0.0.0 to bind to all available interfaces. The configuration file is usually located at

    /etc/nginx/nginx.conf or /etc/nginx/sites-available/default. server { listen 443 ssl; server_name your_domain.com; ... }

    1. Check for Conflicts: Ensure that no other services are using port 443 on the specified IP addresses. You can check this by running sudo lsof -i :443 or netstat -tuln | grep :443.

    2. Restart Docker and Nginx: Sometimes, simply restarting Docker and Nginx can resolve binding issues. You can restart Docker Desktop and then restart Nginx with the following commands:

    sudo systemctl restart nginx

    1. Check Docker Network Configuration: Ensure that Docker's network settings are correctly configured to allow binding to the specified IP addresses. You might need to inspect your Docker network settings or create a custom network.
