Received NO_PROPOSAL_CHOSEN notification from gateway

This error applies to IPsec VPN connections only.

Cause

The remote gateway responded to IKE negotiations from Sophos Connect with this error notification. The possible causes are as follows:

  • The Sophos Connect policy isn't defined or activated on the firewall.
  • The firewall administrator changed the IKE phase 1 proposal used for the Sophos Connect policy on the firewall and the new configuration wasn't exported and uploaded to the client.

Remedy

Contact your firewall administrator and report the problem to troubleshoot further.
