I understand that you've developed a MATLAB Web App that communicates with an Arduino Due and encountering difficulties in sharing the app with other users due to a "connection denied by localhost" or "ERR_CONNECTION_REFUSED" error.
This typically indicates that the server is not configured to accept remote connections.
To enable other users on different computers to access the MATLAB Web App, you'll need to do the following:
1. Configure the Server for Remote Access:
Edit the MATLAB Web App Server configuration file to listen on all network interfaces. This is done by setting the hostname to '0.0.0.0' instead of 'localhost' or '127.0.0.1'.
2. Update Firewall Settings:
Modify the firewall settings to allow incoming connections on the port that the MATLAB Web App Server uses (which by default is 9988).
3. Use the Correct URL:
Instead of using 'localhost', share the URL containing your computer's external IP address with other users.
4. Set Up Port Forwarding:
If the computer is behind a router, you'll need to set up port forwarding to route incoming traffic to your machine.
5. Restart the Server:
After making changes to the server configuration, ensure you restart the MATLAB Web App Server for the changes to take effect.
For more details, refer to the MATLAB documentation on Web Apps:
Hope it helps!
