CurvePreferences includes unsupported curve

Description:

I get "CurvePreferences includes unsupported curve" when I use cloudflared.

  • package version(s): 2024.1.2-1

  • config and/or log files: Jan 20 13:48:20 desktop cloudflared[961]: 2024-01-20T04:48:20Z ERR Failed to create new quic connection error="failed to dial to edge with quic: INTERNAL_ERROR (local): tls: CurvePreferences includes unsupported curve" connIndex=0 event=0 ip=redacted Jan 20 13:48:20 desktop cloudflared[961]: 2024-01-20T04:48:20Z INF Retrying connection in up to 1m4s connIndex=0 event=0 ip=redacted Jan 20 13:48:26 desktop cloudflared[961]: 2024-01-20T04:48:26Z INF Switching to fallback protocol http2 connIndex=0 event=0 ip=redacted

Although it does eventually fall back to a different protocol, this slows down initialization.

Steps to reproduce:

  1. Run "cloudflared tunnel --hello-world" to create a tunnel.

How to fix:

Use Cloudflare's fork of go, as written in the GitHub issue.
