Works for me, thanks for making the app! We had cloudflared installed and working via cli but could not figure what to use for the URL string. All my other servers use localhost:23000 for this but for Start9 you need to use btcpayserver.embassy:80 as pictured to get around the internal Start9 mDNS.

Nice to know cloudflare tunnels can be properly configured on Start9, the app makes it WAAAY easier than installing via chroot. Nice work. 🤙
