Cloudflare One Client for Windows Beta 2026.8.2028.1
A new beta release of the Windows Cloudflare One Client with multiple bug fixes for connectivity, DNS reliability, and UI stability, plus support for routing local IPv4 networks through WARP when enabled by policy. Key improvements include fixed split tunnel issues, better reauthentication reliability, reduced latency during TPM authentication, and elimination of the WLAN AutoConfig service dependency.
A new Beta release for the Windows Cloudflare One Client is now available on the beta releases downloads page.
This beta release includes the following changes and improvements:
- Fixed an issue that could briefly block traffic to split tunnel excluded resources while the client was connecting or reconnecting.
- Improved reauthentication reliability and fixed an issue where a reauthentication could force a new registration.
- Improved client reaction to the current network lowering its MTU.
- Added support for routing non-RFC 1918 local IPv4 networks through the WARP tunnel when unrestricted LAN inclusion is enabled by policy or MDM.
- Improved DNS reliability on networks with lower MTUs by clamping the TCP maximum segment size (MSS) for DNS-over-HTTPS connections sent through the tunnel.
- Improved API reliability by retrying requests dropped when reusing pooled connections.
- The client no longer requires the Windows WLAN AutoConfig service to be running.
- Implemented a service recovery mechanism backed by Windows scheduler task to start WARP service on system unlock if not already started.
- Fixed slow captive portal checks causing the client service to become unresponsive or restart while connecting.
- Fixed a race when switching tunnel protocols during key rotation that could prevent WireGuard from connecting.
- Fixed the client continuing to report 'No network' after a successful manual disconnect.
- Fixed Digital Experience Monitoring (DEX) HTTP tests failing TLS validation on Windows.
- Fixed the client UI crashing at startup when it could not write to the Windows registry.
- Fixed latency spikes and traffic interruptions during TPM-backed API authentication when hardware-backed registration is enabled.
- Fixed trailing whitespace in BIOS serial numbers causing serial-number and client-certificate device posture checks to fail.
- Fixed a client UI crash that could occur when the daemon connection was reset during an IPC request.
- Fixed a startup crash when date formatting data for the system locale had not yet loaded.
