ERROR_IPSEC_IKE_PEER_DOESNT_SUPPORT_MOBIKE - 13904 (0x3650)

Peer does not support MOBIKE.

Updated: Feb 21, 2026

Technical Background

The ERROR_IPSEC_IKE_PEER_DOESNT_SUPPORT_MOBIKE error code is encountered in the context of Internet Protocol Security (IPsec) and its IKEv2 protocol implementation. This specific error indicates that a peer device or endpoint does not support Mobile IPv6 (MOBIKE), which is an extension to IPsec for mobile nodes.

Error Details

  • Error Name: ERROR_IPSEC_IKE_PEER_DOESNT_SUPPORT_MOBIKE
  • Numeric Code: 13904
  • Hex Code: 0x3650
  • Short Description: Peer does not support MOBIKE.

This error is indicative of a capability issue, where the peer device or endpoint lacks the necessary support to handle Mobile IPv6 extensions in IPsec/IKEv2 communications. The presence of this error suggests that the communication between two endpoints may be compromised due to missing features on one side.

Common Causes

  • Unsupported Operations: The peer device does not implement MOBIKE, which is required for certain types of mobile node scenarios.
  • Incorrect Usage Context: The operation context or configuration might require MOBIKE support that the peer cannot provide.

Real-World Context

In a typical scenario, this error would be encountered when attempting to establish an IPsec/IKEv2 connection where one endpoint expects MOBIKE support from the other. This could occur in environments with strict security policies or legacy devices that do not support modern IPsec extensions.

Is This Error Critical?

The criticality of this error depends on the specific use case and requirements. If MOBIKE is a mandatory feature for your communication, then this error can be considered critical as it prevents the establishment of a secure connection. However, if MOBIKE support is optional or not required, the impact may be minimal.

How to Diagnose

  1. Review Operation Context: Ensure that both endpoints are configured correctly and that the operation context supports the use of MOBIKE.
  2. Validate Parameters: Check for any configuration parameters that might require MOBIKE support.
  3. Confirm Object Types: Verify that the peer device is capable of supporting MOBIKE, as some devices may have limitations or be incompatible with this feature.
  4. Verify Input Data: Ensure that all input data and configurations are correct and do not inadvertently disable MOBIKE support.

How to Resolve

  1. Correct Parameter Usage: Adjust any parameters that might be incorrectly configured to ensure they support MOBIKE if required.
  2. Adjust Operation Context: Modify the operation context or configuration to accommodate the peer's limitations, possibly by disabling MOBIKE support if it is not critical for your use case.
  3. Restore Data: If data corruption or misconfiguration is suspected, restore the correct settings and configurations.
  4. Retry Operation with Valid Inputs: Attempt to establish the connection again using valid inputs that do not require MOBIKE support if it is not essential.

Developer Notes

Developers should ensure that their applications are capable of handling both scenarios: where MOBIKE is supported and where it is not. This can be achieved by implementing fallback mechanisms or providing user options to disable MOBIKE when necessary.

Related Errors

  • ERROR_IPSEC_IKE_PEER_CERTIFICATE_NOT_VALID: Indicates issues with the peer's certificate, which might affect secure communication but does not directly relate to MOBIKE support.
  • ERROR_IPSEC_IKE_NO_PRIVATE_KEY: Indicates a lack of private key for establishing an IPsec connection, unrelated to MOBIKE support.

FAQ

Q: What is MOBIKE?

MOBIKE stands for Mobile IPv6 Extension for IP Security. It allows mobile nodes to maintain secure IPsec connections while moving between different network locations.

Q: How can I check if my device supports MOBIKE?

You can check the documentation or specifications of your device to determine its support for MOBIKE. Additionally, you may need to query the device's capabilities through management interfaces or APIs provided by the manufacturer.

Q: Can this error be ignored in certain scenarios?

Yes, if MOBIKE is not a critical requirement for your communication, this error can be ignored and the connection might still be established using other IPsec/IKEv2 features. However, it is recommended to address any missing capabilities to ensure full functionality.

Summary

The ERROR_IPSEC_IKE_PEER_DOESNT_SUPPORT_MOBIKE error indicates that a peer device does not support MOBIKE, which can impact the establishment of secure IPsec/IKEv2 connections. This error should be diagnosed and resolved by ensuring correct configuration and operation context, or by adjusting parameters to accommodate the limitations of the peer device.
