Docker Unable to connect to localhost - docker

Question

I'm trying to dockerise a symfony2 application. The container is up and running without any errors. However, I'm getting 'An error occurred during a connection to localhost' when I hit http://localhost:8081 in the browser
docker-compose.yml
version: "3.8"
services:
app:
container_name: "${PROJECT_NAME}"
build:
context: .
dockerfile: ./Dockerfile
restart: 'always'
ports:
- 8081:80
volumes:
- .:/var/www/html
- ${LOG_DIR-./logs/apache2}:/var/log/apache2
Dockerfile
FROM php:7.0-apache
RUN a2enmod rewrite
COPY ./000-default.conf /etc/apache2/sites-available/000-default.conf
// installing php extensions / libraries and composer ..
EXPOSE 80

I generated ssl certificates(referred to https://medium.com/#nh3500/how-to-create-self-assigned-ssl-for-local-docker-based-lamp-dev-environment-on-macos-sierra-ab606a27ba8a) and updated the files as below
000-default.conf
// added this to my existing 000-default.conf (pls refer to the question)
<VirtualHost *:443>
DocumentRoot "/var/www/html/web"
ServerName localhost
SSLEngine on
SSLCertificateFile "/etc/apache2/ssl/server.crt"
SSLCertificateKeyFile "/etc/apache2/ssl/server.key"
<Directory /var/www/html/web>
<IfModule mod_rewrite.c>
Options -MultiViews
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^(.*)$ app_dev.php [QSA,L]
