I have checked with my blog and the Adsense ELigibility Checker is showing 500 error code. But the website working properly on the other hand on all the browsers without any error.
Can you share the screenshot? Also share your website URL?

I realized that this happens when it's on the cloudflare, I just don't know how to disable the firewall there, but it shouldn't be difficult.
The cloudflare firewalls block traffic from entering the site, I decided, removing it. but everyone will choose what they want, there is a configuration to be done in the cloudflare, but I ended up not doing it.
