The “critical issues” are all a result of the fact that we don’t support CA Chains on free hosting. There isn’t a way around that, sadly.
That said, most sites never experience any issues because of this. Just because Health Check can’t connect to the WordPress API doesn’t mean your browser can’t either.
Ok thank you very much!!!
However, all the problems I showed you above in addition to the lack of PHP Imagick Extension that it’s not supported in free infinityfree.net hosting as I know they disappeared after the Frond End PM update from v11.3.1 to 11.3.3
