Version

5.4.3

Details & Steps to reproduce

I am on a machine, which is firewalled from the internet. I only use it locally.

I get the following error when accessing 2fauth.

2025/03/16 20:46:20 [error] 41#41: *1 upstream timed out (110: Operation timed out) while reading response header from upstream, client: 192.168.208.1, server: 2fauth, request: "GET / HTTP/1.1", upstream: "fastcgi://127.0.0.1:9000", host: "2fauth.xxxxxx.com"

Which "upstream" is it trying to access, is there a specific domain I need to whitelist for 2fauth to work?

Expectation

2fauth should work without internet connection.
