If your VPN connection stopped working after updating to macOS 26 Tahoe, it’s likely due to Apple removing support for older VPN algorithms in the built-in IKEv2 and IPSec clients. Common issues include deprecated encryption types like DES, legacy SHA1 authentication, and outdated Diffie-Hellman groups (e.g., Group 2).

These changes impact many VPN setups — especially those using firewalls and gateways from vendors like Cisco, SonicWall, or Fortinet — and typically result in errors like “No acceptable proposal found” or silent connection failures.

VPN Tracker 365 offers full support for these legacy VPN settings, allowing you to reconnect without modifying your existing VPN gateway. Learn how to restore your VPN connection by following this step-by-step guide.
