Cloudflared 2024.1.1 prevents our dns from working


our company is using cloudflare zerotrust and it’s working pretty well until today’s update to 2024.1.1. We don’t have any relevant logs to share, since cloudflared was not showing anything irregular, and our internet dns relays were internally working as expected as well.

But no client dns request went through the cloudflare tunnel to our internal dns server. We only recovered from this downgrading the cloudflared version back to what was running previously (2023.8.2).

Any pointers regarding troubleshooting this would be much appreciated. Right now we’re running cloudflared with --no-autoupdate to prevent further network issues.

Thanks in advance!
