When you check your InfinityFree SSL certificate with online SSL checker tools, you might see a warning like this:
The certificate is not trusted in all web browsers. You may need to install an Intermediate/chain certificate to link it to a trusted root certificate.
This warning sounds scary, but it’s actually not a problem for your website visitors.
What this warning means for your site
You can safely ignore this warning. Your site will work perfectly fine with HTTPS for virtually all modern browsers and devices.
The warning appears because SSL checker tools and some programmatic access methods are very strict and look for the “perfect” SSL setup that includes all intermediate certificates. Your actual website visitors won’t experience any problems because their browsers can automatically handle the missing pieces.
Why this happens
When SSL certificate providers issue your certificate, they also provide additional files called intermediate certificates. These act as a bridge between your certificate and the root certificate authorities that browsers trust.
Modern browsers automatically fetch these intermediate certificates when needed, so websites don’t have to provide them. This is why your SSL works fine for visitors even though the checker tool complains about missing intermediate certificates.
What should I do about this?
Nothing. Your SSL certificate is working correctly for your visitors, even though the SSL checker tool shows a warning.
If you want to eliminate this warning completely, you would need to install the intermediate certificate files. However, this feature isn’t available on free hosting accounts. Installing intermediate certificates is only supported on premium hosting plans.
For most websites on free hosting, the current SSL setup works perfectly for actual visitors. The warning only affects SSL testing tools and programmatic access, not your website’s normal operation.
This SSL checker warning is different from actual SSL problems like missing certificates or incorrect domain configuration. If your website visitors see browser security warnings when accessing your site, that’s a separate issue. Feel free to create a topic in Hosting Support if you need help with that.
