Troubleshooting TLS Certificate Verification Errors

Overview

When connecting to our services, you might encounter a TLS certificate verification error. This error typically indicates an issue with the SSL/TLS certificate being used for the connection. The error message may look like this:

TLS Error: Failed to verify certificate Details: x509: certificate signed by unknown authority (Nylas::NylasApiError)

Potential Causes

1. Self-Signed Certificate or Untrusted Certificate Authority (CA):

   • The certificate might be self-signed or not issued by a trusted CA.

2. Issues with the Trust Chain:

   • There might be a problem with the certificate chain that prevents it from being recognized as valid.

3. Expired or Not Yet Valid Certificate:

   • The certificate might have expired or is not yet valid according to its validity period.

4. Network Issues or Misconfigured Certificate Settings:

   • Network configurations or settings related to the certificate might be incorrect.

Possible Solutions

1. Ensure the Certificate is Signed by a Trusted CA:

   • Check if the certificate is signed by a widely recognized and trusted CA. If it's self-signed, consider replacing it with a certificate from a trusted CA.

2. Verify the Certificate's Validity Dates:

   • Ensure that the certificate is currently valid. You can check the start and end dates of the certificate's validity period to confirm it hasn't expired.

3. Examine the Trust Chain:

   • Verify the complete chain of trust for the certificate. Ensure that all intermediate certificates are correctly installed and that the chain leads back to a trusted root CA.

4. Check Network Configurations:

   • Ensure there are no network issues affecting certificate validation. Confirm that the client and server are correctly configured to handle SSL/TLS connections.

5. Consult Your Certificate Provider or Administrator:

   • If the above steps don't resolve the issue, contact your certificate provider or system administrator for further assistance.
