[Solved by itself] Well-known returns 404 for letsencrypt but it is OK for me

My domain is: noonlordhost.com

My web server is (include version): nginx

The operating system my web server runs on is (include version): ubuntu 20.04

I can login to a root shell on my machine (yes or no, or I don't know): yes

I'm using a control panel to manage my site (no, or provide the name and version of the control panel): no

The version of my client is (e.g. output of certbot --version or certbot-auto --version if you're using Certbot): latest acme.sh v3.0.3

I can get the wellknown from browser, curl, wget just fine but acme.sh says that it returned 404. I copied and pasted the url in my browser and it returned the file. This is the URL: http://noonlordhost.com/.well-known/acme-challenge/EssidhLBQ5ZwnvTEITflvZr-KDlas2CZNp31XkaMIWQ
