How to capture https traffic to local server?

I have a local server for testing purposes on with certificate from Let’s Encrypt.

Also I add a domain name in my hosts file:

Now I want to capture traffic from my desktop app to this server.

Postman and system are configured as described here:

Capturing of https traffic is working well for Internet sites, but does not working for my local site. Both for desktop app and browser - I just get “This site can’t be reached” error.

What should I do to make it working?

Postman v 9.0.7
