### Dify version

1.15.0

### Cloud or Self Hosted

Self Hosted (Docker)

### Steps to reproduce

- Visit the console Dify page "${CONSOLE_WEB_URL}/"
- The webpage redirects between `${CONSOLE_WEB_URL}/`, `${CONSOLE_WEB_URL}/auth/refresh` and `${CONSOLE_WEB_URL}/signin` infinitely, as the following video shows:

Note:

1. This bug is not always reproducible.
2. I doubt this is related to expired access token. Once I have noticed that the `/console/api/account/profile` and `console/api/refresh-token` returned 401 before the infinite loop.

### ✔️ Expected Behavior

The console ui displayed without any issue.

### ❌ Actual Behavior

Infinite redirection, visit `${CONSOLE_WEB_URL}/` or `${CONSOLE_WEB_URL}/apps` does not resolve this issue.

Start by reproducing the loop from the console URL and inspect the redirects among /, /auth/refresh, /signin, /console/api/account/profile, and /console/api/refresh-token, especially after a 401. Trace the access-token refresh and sign-in flow until the redirect decision is clear; done means the console loads without an infinite redirect while expired credentials are handled normally.
