Hey @FlankerZzzz! 👋 I'm here to help you with any bugs, questions, or contributions you have for the DIFY project. Let's get this issue sorted out together!

I found a similar issue where users experienced the same problem with the 'run app' feature not reflecting the updated Nginx port. The solution involves ensuring that the EXPOSE_NGINX_PORT environment variable is correctly set and that the application code uses this variable to construct the URL.

To resolve this, you can modify the code in index.tsx to include the port in the URL. Here's a suggested solution:

  1. Update the code in index.tsx to construct the URL with the port:

    const appBaseURLWithPort = `${appDetail.site.app_base_url}:${process.env.EXPOSE_NGINX_PORT}`;
const appUrl = `${appBaseURLWithPort}/${getWebAppType(appDetail.mode)}/${appDetail.site.access_token}`;

  2. Ensure that the EXPOSE_NGINX_PORT environment variable is set in your .env file:

    EXPOSE_NGINX_PORT=43980

This should ensure that the 'run app' button generates the correct URL with the port included [1].

Modify .env then recreate the nginx container:
NGINX_PORT=3010
EXPOSE_NGINX_PORT=3010
