Steps to reproduce

Unable to Access Self-Hosted Dify via IPv6 Address or Domain Name
I have modified the listening domain and port of Nginx for my self-hosted Dify instance. Access via IPv4 address works normally, but access via IPv6 address and domain name fails. When using curl to test the IPv6 address, it returns the following response:
plaintext
HTTP/1.1 307 Temporary Redirect
Server: nginx/1.29.1
Date: Fri, 19 Sep 2025 09:34:02 GMT
Connection: keep-alive
location: /apps
However, the page still cannot be opened in the browser.
