🐛Quick Tunnels' DNS Lookups to [::1]:35

[Johnathan31]

Hey Cloudflared devs 👋

I've been trying to use the Quick Tunnels service for quick deployment.

But every time I'd make a quick tunnel, I get this error message:

failed to request quick Tunnel: Post "https://api.trycloudflare.com/tunnel": dial tcp: lookup api.trycloudflare.com on [::1]:53: read udp [::1]:44994->[::1]:53: read: connection refused

In fact, this problem occurs in every request to the host api.trycloudflare.com.

Full Installation command

wget --no-check-certificate https://github.com/cloudflare/cloudflared/releases/latest/download/cloudflared-linux-arm64 -O cloudflared > /dev/null 2>&1

Used command

./cloudflared tunnel -url <URL> --log-file <FILE.log>

Environment and versions

• OS: Android
• Terminal tool: Termux
• Architecture: Aarch64
• Version: v2026.6.1
• Insallation: Official Github Release
• Installation URL: https://github.com/cloudflare/cloudflared/releases/latest/download/cloudflared-linux-arm64

Other contexts

• I can't directly share the project files or code for a few reasons, but the server is a PHP server, serving an HTML file.
• nslookup api.trycloudflare.com succeeded.
• I ran a standalone Go file using net.LookupHost, which resolved properly:

package main

import (
    "fmt"
    "net"
)

func main() {
    ips, err := net.LookupHost("api.trycloudflare.com")
    fmt.Println(ips, err)
}

• $PREFIX/etc/resolv.conf contains valid nameservers.
• CODEBUG=netdns=go+1 reports:

Go package net: using the Go DNS resolver.

• Go is version go1.26.3
