Cloudflare Tunnel creates secure, encrypted connections between your local network and Cloudflare's network. DNS record issues often arise when Cloudflare can't resolve the domain name associated with your tunnel, preventing traffic from flowing correctly. This can be due to misconfigured DNS settings, Cloudflare's DNS servers having trouble resolving, or temporary DNS propagation delays.
