The error code 0x000035fa, called Error_Ipsec_Ike_Invalid_Key_Usage, means there's a problem with the way digital certificates are used for secure connections.
This can happen if the certificates are set up wrong, are self-signed, untrusted, or have expired. When this error occurs, it can cause VPN connections to fail and lead to service interruptions, which can be risky for network security.
To fix it, check the certificates, reissue them if needed, and make sure they come from trusted sources. Regularly checking and managing certificates can help avoid this problem in the future.
Error meaning:
The error "Ipsec Ike Invalid Key Usage" means there is a problem with the digital certificates used for secure connections.
They don't have the right permissions for their tasks, making it hard to set up a safe connection.
Causes:
The "Ipsec Ike Invalid Key Usage" error might occur on your system due to the following reasons:
- Key usage attributes in the certificate are set up incorrectly.
- The certificate is self-signed or from an untrusted Certificate Authority (CA).
- The certificate has expired or has been revoked.
- There is a mismatch between what the certificate is meant for and how it is actually used in the IPsec setup.
- Poor management of certificates can lead to these errors.
Symptoms:
Symptoms of the "Ipsec Ike Invalid Key Usage" error include:
- Failed VPN Connections: Users can't connect to secure networks.
- Error Messages: Messages show up when trying to set up an IPsec tunnel, indicating problems with certificates.
- Dropped Connections: Users might lose their connection suddenly.
- Intermittent Service Disruptions: Connections may work sometimes and fail at other times.
- Alerts in Monitoring Tools: Security tools might warn about possible weaknesses in the network.
- Compromised Data Integrity: Important information could be at risk.
- Compromised Confidentiality: Private data might not be secure.
It's important to fix these issues quickly to keep the network running smoothly.
Solutions:
Step 1: Check the Certificate
Make sure the certificate you are using for IKE authentication has the right key usage.
It should allow for digital signatures and key encipherment.
Step 2: Reissue or Replace the Certificate
If the certificate does not meet the correct key usage, you will need to reissue it or get a new one that does.
Step 3: Inspect the Certificate Chain
Look at the certificate chain to check for any problems that might affect its validity.
Step 4: Trust the Certificate Authorities
Ensure that the Certificate Authorities (CAs) used in your certificate are trusted within your network.
Step 5: Update Your VPN Device
Update the firmware or software of your VPN device to the latest version to fix any bugs related to the error.
Step 6: Test the Connection
After making all these changes, test your VPN connection to make sure the error is fixed.

What Are Common Scenarios That Trigger This Error?
This error can happen for a few reasons. It might be caused by security settings that are not set up correctly, certificates that are meant for other uses, or certificates that have expired. Also, using old or unsupported ways to encrypt data can cause problems too.
How Does This Error Affect VPN Connections?
The error causes big problems for VPN connections. It makes it hard for users to connect safely, which can lead to not being able to use the internet properly. This can also create security risks because the information might not be protected well.
Can This Error Occur on Mobile Devices?
Yes, this error can happen on mobile devices. If the certificates used for VPN connections have wrong settings, it can stop the secure connection from working. This means you might not be able to use the VPN on your phone or tablet.
Are There Specific Operating Systems More Prone to This Error?
Some operating systems, especially older ones with weak security settings, are more likely to have problems with certificate keys. Keeping your system updated and following good security habits can help reduce these issues.
How Can I Verify My Certificate's Key Usage Settings?
To check your certificate's key usage settings, use tools like OpenSSL or your computer's certificate manager. Look for the Key Usage and Extended Key Usage sections to make sure everything is correct. This helps ensure your certificate works properly.
