Troubleshooting Proxy Issues with Mixpanel and Caddy Configuration

Hey everyone, I have a weird difficulty setting up a proxy for mixpanel. Not sure if I should be technical here or not, but I've set up Caddy as a proxy but it seems to not forward the IP making the city and country column empty in mixpanel. Is this a known issue or how can I resolve? I could post my caddy configuration if I'm allowed to be technical in this channel. Thanks a lot for your help.
