Invalid url prefix in /etc/nginx/sites-enabled?

Question

Nginx

/etc/nginx/sites-enabled not working. The error refers to line 17 - proxy_pass. The code is in the photo, because I work through VMWare and I can’t copy

Answer 1

proxy_pass http(s)://letstt;because. Well, just writing in the server block listen 443without configuring HTTPS later is strange.
I suggest you figure out how nginx works in general, so that you don’t get such vermicelli.
