Setup

Enable HTTPS

Create Application: Set the external address to https://2fauth.example.com (please replace the domain name according to your actual situation).
Create Reverse Proxy Site: Set the proxy address to http://127.0.0.1:8000 (please replace the IP and port according to your actual situation).
Apply for Certificate: Create a certificate for 2fauth.example.com, choose HTTP as the verification method.
Enable HTTPS: Go to the website settings page, click on HTTPS, select the certificate you just added and save.

If HTTPS is not enabled, it will cause issues such as inability to scan QR codes. In this case, the external address can be directly set to http://192.168.10.100:8000 without the need for reverse proxy settings.
