0x00003604 – Error_Ipsec_Ike_No_Public_Key – Peer’s Certificate Did Not Have a Public Key

The error code 0x00003604, known as "Ipsec_Ike_No_Public_Key," means that a peer's digital certificate is missing a public key, which is important for secure connections.

This can happen if the certificate has expired, if there are mistakes in how the Certificate Authority is set up, or if firewalls block it. If this error occurs, you might not be able to connect to a VPN, which can leave your data unsafe.

To fix this, check if the certificate is valid and make sure all settings are correct. Being aware of this issue can help keep your online activities safe.

Error meaning:

The error "Ipsec_Ike_No_Public_Key" means a device couldn't find the public key needed to create a secure connection.

This prevents a Virtual Private Network (VPN) from working properly and keeps information from being safely shared over the internet.

Causes:

1. The peer's digital certificate does not have a valid public key.
2. The certificate authorities are set up incorrectly.
3. The digital certificates have expired.
4. Firewall settings are blocking important protocols.
5. There are compatibility issues with different encryption standards.
6. Configuration settings are incorrect.
7. The software being used is outdated.

Symptoms:

Symptoms of "Ipsec_Ike_No_Public_Key" Error:

7. Drops in internet connectivity happen.
8. Complete inability to access secured resources.
9. Logs or alerts show failures in IKE (Internet Key Exchange) processes.
10. Overall frustration for users needing secure remote access.

Solutions:

Step 1: Check the Peer's Certificate

Make sure the certificate from the other end of the VPN is set up correctly and has a valid public key.

Step 2: Verify Certificate Authority (CA) Settings

Ensure that both sides of the VPN are using certificates signed by a trusted Certificate Authority (CA).

Step 3: Inspect Certificate Expiration Dates

Look at the expiration dates on the certificates.

If any are close to expiring, make sure to renew them.

Step 4: Check Cryptographic Settings

Make sure that both sides of the VPN are using the same encryption and hashing methods.

The "Ipsec_Ike_No_Public_Key" error is commonly associated with Windows operating systems, particularly Windows 7, Windows 8, Windows 10, and Windows Server versions.

This error can also occur in software that uses IPsec for secure communications, like certain Virtual Private Network (VPN) applications.

The error happens when there is a problem with the certificates used to create secure connections, specifically when a certificate is missing a public key.

This can make it unsafe to send private information over the internet.

Prevention:

How to Avoid the "Ipsec_Ike_No_Public_Key" Error:

1. Check Certificates: Make sure all certificates used in your IPsec/IKE setups are valid and have public keys.
2. Regular Audits: Look at your certificates often to ensure they haven't expired or been set up incorrectly.
3. Update Certificates: Renew your certificates before they expire to keep everything running smoothly.
4. Use a Good System: Implement a strong certificate management system to help you issue and renew certificates easily.
5. Choose a Reliable CA: Make sure your Certificate Authority (CA) is trustworthy and follows the right rules for creating and storing keys.
6. Monitor Usage: Set up logging and monitoring to catch any unusual activities with your certificates.
7. Train Your Team: Provide regular training for network administrators on how to manage certificates and avoid errors.

What Software or Devices Commonly Encounter This Error?

Many devices and software, like VPNs, firewalls, and remote access programs, often face problems with certificates. These issues happen because of wrong settings or missing keys, which can affect secure communication and the safety of data in networks.

How Does This Error Affect VPN Connections?

This error can stop VPN connections from working. Without a good public key, the computers can't trust each other, which means they can't connect safely. This can lead to problems like not being able to connect and the chance of data getting exposed.

Is This Error Specific to Certain Operating Systems?

This error can happen on Windows, Linux, and macOS. It may look different and be fixed in various ways depending on the security settings and VPNs used in each system. Each operating system can have its own way of dealing with this error.

Can This Error Occur With Self-Signed Certificates?

Yes, this error can happen with self-signed certificates. If the certificate doesn't have the right public key or if the system doesn't trust it, you might get errors when trying to connect or authenticate.

What Is the Recommended Logging Level to Troubleshoot This Error?

To fix this error, set the logging level to 'debug'. This helps you see a lot of details about what is happening with the certificate checks. It makes it easier to find and fix problems that might be causing the error.
