 2. `proxy_pass` value must be changed from `http://host.docker.internal:3000` to `http://localhost:3000`
 3. Generate the certificates manually via `mkcert`. Check the command in `start-https-server.sh` file.

Some Linux distros (`Ubuntu` for example) have installed and running `apache2` webserver on port `80`. This can result in `Address already in use` error (you can check with `docker logs wildcard-nginx`). Simple solution for this is simply turning it off temporarily with `sudo systemctl stop apache2`. After that just run `./start-https` again.
