Please describe your issue in as much detail as possible:

I set up a service using Caddy to locally reverse proxy requests to Steam.
I modified my hosts file to point the addresses to my local machine.
I used a self-signed certificate, placed it in the ‘ /etc/ca-certificates/trust-source/anchors/ ’ directory, and also added the certificate to the ‘ ~/.pki/nssdb ’. However, the built-in browser still shows an "Invalid SSL Certificate (error:-202 status:4)." error.

Hello @Traveller-hongchen, we can't sensibly support hijacking SSL connections.

Closing as won't fix.
