<Tab label="Ubuntu/Debian">

The default firewall configuration tool for Ubuntu is ufw. Since Debian doesnot install ufw by default, 
it can be installed using

```bash
sudo apt install ufw
```

First check whether port 443 is already open using

```bash
sudo ufw status verbose
```

</Tab>

<Tab label="CentOS/RHEL">

The default firewall tool on onRHEL 8 / CentOS 8 servers is firewalld (Dynamic Firewall Manager).
Check if https is already enabled using

```bash
sudo firewall-cmd --zone=public --list-ports
```

If you see `https` in the output then it's enabled. If not use the following commands to enable

```bash
sudo firewall-cmd --permanent --add-service=https --zone=public
sudo firewall-cmd --reload
sudo firewall-cmd --list-services --zone=public
```

Then reload firewalld using

```bash
sudo firewall-cmd --reload
```
