My domain is: simca.tech

I ran this command: sudo certbot --nginx

It produced this output:

Hi @steven4389

checking your domain you see a part of the problem ( https://check-your-website.server-daten.de/?q=simca.tech ):

Port 80 is open. But there answers a

X-Powered-By: Express

not a nginx. So Certbot may have created the correct validation file, but your application doesn't send that file.

PS: There is

Visible Content: </app-root>

as content visible, instead of the expected http status 404 - Not Found.

The community software hides that.

hi man, what must i to that my site send the file

Please check

If you want to use http-01 validation, Certbot must be able to create a validation file, Letsencrypt checks that file via

http://simca.tech/.well-known/acme-challenge/random-filename

So easiest solution. Find your webroot / documentroot, create the two directories .well-known/acme-challenge, there a file (file name 1234), then check if you can load that file via

http://simca.tech/.well-known/acme-challenge/1234

Try, if that works.
