Yes, it is a similar problem.
For the moment, I need to host my web server on my first IP address on port 80, and my node.js application on the second IP address on port 80 also. But actually Nginx is running on port 80 on both IPs, I have changed every Nginx and http configuration files in the system, but it is still the same.
Please let me know any hack I can use to work around this.
Thanks
