403 Error during self-diagnosis

Hi,

I am facing issue during the self-diagnosis step of setup wizard. it displays the following errors:

Checking page optimization requests: Failed

I have been using this plugin for a while. I tried it on multiple websites, and it worked flawlessly, but this time I used it on a website on a free hosting (infinity free). Maybe that’s causing an issue?
