Error 1000 running Tinyproxy Via Argo Tunnel

I’m running tinyproxy as a forward proxy to access the internal LAN but my network is behind a CGNAT, so I have no public ip address. To remedy this issue I thought about using Cloudflare’s argo tunnel using cloudflared. I ran tcpdump and I could see that traffic was being sent to tinyproxy. I disabled the Via Header in the tinyproxy conf file but that didn’t fix the issue. Any suggestions on how to fix this issue?
