TL;DR: Have 1 address abc.123.com. when I am running dev server locally, route to me. If not, route to another address.

Long version
UnInbox, has some long running servers that live in a vps and send out webhook messages

I need a proxy with failover capabilities to live permanently online (vps is fine)
when the app is running locally on my machine, it will route to me
when im not, it will route to another web server

I tried with Cloudflare Tunnels and CaddyServer
i can access the tunnel directly using https://tunnelAddress.mydomain.dev

CaddyServer installed on a vps and given it the following config

proxy.mydomain.dev {
reverse_proxy * {
                to https://tunnelAddress.mydomain.dev https://failover.mydomain.dev
                lb_policy first
                lb_try_duration 5s
                lb_try_interval 250ms

                fail_duration 30s
                max_fails 1
                unhealthy_status 5xx
                unhealthy_latency 2s
                unhealthy_request_count 1
        }
}

the path https://tunnelAddress.mydomain.dev works fine when accessed directly - validating that the tunnel is up
when accessing via proxy.mydomain.dev i get an error ERR_TOO_MANY_REDIRECTS
