How to fix 404 error on Wordress?

Question

open server

Transferred a site to Wordpress from a personal PC to a local server on a Windows server 2016 inside the company's local network. IE Enhanced Security mode is disabled.
Successfully installed the open_server_5_2_8_basic version engine on Windows server 2016.
The default localhost starts without problems.
Created .htaccess

# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>
# END WordPress

The domain name on the working PC and the local server where the site will work are identical.
I go to my sites - the desired domain. But instead HTTP Error 404. The requested resource is not found. And so in any browser.
The domain was registered in hosts.
I tried to start pure Wordpress, the start page of the engine installation opens successfully.

Answer 1

The problem was in port 80 being occupied by the server's system process.
Because of this, I moved the Open Server to port 8080 and the site stopped working.
I found this solution:
You can free up port 80 occupied by system in windows in the following way.
Win + R, enter "regedit" (without quotes).
We are looking for the “HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\HTTP” branch.
We change the value of the “start” key from 3 to 4 ... before that I met advice to set 0. So zero did not help me.
We restart the computer.
We are glad that we found the necessary information so quickly.
P, S- BEWARE! Apache will work - the network printer will stop working.
Can someone tell me how to make wordpress friends with ports other than 80
