What is a Certificate Chain?
Browsers need to verify that your SSL certificate was issued by a trusted Root CA. This verification follows a "chain of trust" involving one or more Intermediate Certificates.
If your server sends an incomplete chain (missing intermediates), some devices (especially mobile or older browsers) may show security warnings. Use this tool to ensure you have the full bundle.
