Port 443 is blocked and not working
I have tried everything
sudo a2enmod ssl
sudo a2ensite default-ssl
sudo /etc/init.d/apache2 restart
Also ufw 443 is also not working
My security groups configuration for 443 is for inbound and outbound
Please help!! Also note that I am not able to install anything via apt as well as it stucks from 0% installation
The issue looks like in firewall-cmd
When I use this command :
sudo netstat -tulpn | grep :443 It gives output tcp 0 0 172.31.40.53:443 0.0.0.0:* LISTEN 5138/nginx
I can not use the firewall-cmd command as firewalld is not installed and can not able to install it as it shows only this
apt install firewalld Reading package lists... Done Building dependency tree

and then timeout
ACL tables have added htttps rule in inblud and outbound , so that one is ok. Need to fix the issue with firewall , can you help how to access firewall without commandline and also without plesk , as plesk is expired.
The subnet's network ACL is stateless inspection and must allow return communication. Therefore, you need to allow well-known ports in the inbound and outbound rules as shown below.
I hav edited my question, Also Network ACL's are done as per you as well with inbound and outbound rules.
