Network error on self hosted

[ShaAlexander]

I am reaching out to seek assistance with a network error that I am encountering on my test page. I have performed the necessary setup and configuration, but unfortunately, I am still experiencing issues.

Here are the details of my setup:

Server: Nginx
Domain: speedtest.easyvoicetelecom.nl
I have followed the instructions provided and added the nginx configuration settings according to your guide.

I also created an account and verified the domain.

So what am I missing here?
I have added a screenshot not that it help much but all the files are there.
