GTmetrix error see picture joined

Other Information

I have setup a brand new joomla 4 site with the example data, directly downloaded from joomla.org. Everything is standard from origin. I have a ssl certificate from zerossl, I got from Infinityfree services. No htaccess tuning yet. No cache.
I try to check the basic performance. GTmetrix tells they cannot acess to the site. Any idea to test ? Thanks for attention.

use this WebPageTest Test - Running web page performance and optimization tests...

You’re welcome
I think GTmetrix actually hits on this

Ensuring only web browsers can access your website

InfinityFree is a website hosting service. That means that the hosting accounts we provided are intended for hosting websites. Websites contain pages that are accessed through web browsers. InfinityFree is not intended to be used for file sharing, API hosting, database hosting or background tasks/tools.

This issue is actually related to this:

Warning: "The certificate is not trusted in all web browsers"

If you have installed an SSL certificate on InfinityFree, you may want to use an SSL Checker tool to verify your SSL certificate was installed correctly. However, when doing so, you see an error 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. Learn more about this error. The fastest way to fix this problem is to contact your SSL provider. What does this warning mean for your sit…

For some strange reason, GTMetrix requires an intermediate/chain certificate (which is not supported on free hosting) to be installed in order to perform the test, as explained on their site: General GTmetrix Test Errors | GTmetrix

I tried 10+ addresses that I found on the forum and that they belong to free subdomains
and explicitly stated http:// in the address
(and only those that do not force https - no redirection)
and for everything it gave me that error about the certificate
so at first I thought they were blocked.

I think there was a bug with them, because now everything works properly when the http version is requested, which has nothing to do with certificates.
