The troubleshooting information describes some typical problems that you might encounter in configuring and establishing your IPsec tunnels, and the suggested actions for how to resolve the problems.
Problem | Suggested action |

Your device has previously connected, but cannot reestablish the tunnel |
Check the settings for your tunnel against the supported settings. In particular, check you are using supported DH group settings. When incorrectly set, these settings can cause problems at the renegotiation stage. Clear the IPsec security associations on your device, and attempt to re-establish the tunnel. Tip: While testing, temporarily set the Lifetime value for your connection to a low value (such as 10 minutes) to check whether the tunnel can successfully re-establish.
Once the tunnel is re-establishing correctly, revert the lifetime to the recommended value.
