Dify version

Version 1.1.3

Cloud or Self Hosted

Self Hosted (Docker)

Steps to reproduce

  1. Change nginx port, e.g.,
$ diff .env .env.example 
930,931c930,931
< EXPOSE_NGINX_PORT=12580
< EXPOSE_NGINX_SSL_PORT=12443
---
> EXPOSE_NGINX_PORT=80
> EXPOSE_NGINX_SSL_PORT=443
  1. Open an application
  2. Click open "Publish" and "Run App"

✔️ Expected Behavior

Redirect to the right URL with port.

❌ Actual Behavior

The new opened page contains the URL without the port, and then fails to connect.

Could be related in web/app/components/app/app-publisher/index.tsx:

  const appDetail = useAppStore(state => state.appDetail)
  const { app_base_url: appBaseURL = '', access_token: accessToken = '' } = appDetail?.site ?? {}
  const appMode = (appDetail?.mode !== 'completion' && appDetail?.mode !== 'workflow') ? 'chat' : appDetail.mode
  const appURL = `${appBaseURL}/${appMode}/${accessToken}`

Hey @Inokinoki! I'm Dosu, your friendly bot here to help you solve bugs, answer questions, and navigate your way to becoming a contributor while you wait for a human maintainer. Let's tackle this together! 🚀

I found a similar open issue that might be related to your problem. The issue suggests modifying the app_base_url to include the port in the URL. You can update the code in index.tsx as follows:

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

Additionally, ensure that the EXPOSE_NGINX_PORT environment variable is set in your .env file:

EXPOSE_NGINX_PORT=12580

This should ensure that the Run App button generates the correct URL with the port included [1].
