 I decided to test if I can access Hideout over HTTPS, and if I'll be redirected when I attempt HTTP connection. I found the website timing out. After checking every corner, it turned out that on my firewall, I've only setup port-forwarding for port 80, but not port 443. After I forwarded port 443, the HTTPS connection and redirection worked immediately.
 
-At this point, I've successfully hosted a working instance of Hideout on my laptop. But if I'm to send a Hideout link to others, I'd expose the public IP of my home to both the recipients, and the unprivate platform where I send the link. So I need to host Hideout behind a VPN. Fortunately, port-forwarding is supported by Mullvad VPN: https://mullvad.net. I installed its open-source app on my laptop, and followed Mullvad's port-forwarding guide: https://mullvad.net/en/help/port-forwarding-and-mullvad/. Overall, it was a rather simple process. A caveat is that Mullvad assigns me a random port number. Let's assume it's 50000 in this guide.  Before it would work, I disabled the port-forwarding on my firewall for port 80 and 443, and instead enabled port-forwarding for port 50000. Then I updated the DNS of the domain to point to the "Out" IP of Mullvad, which can be seen by clicking the expand arrow on the app's home interface. The new port also required me to change the `listen 443 ssl` in `hideout-demo.com.conf` to `listen 50000 ssl`. Below is the final config. Notice the commented block at the end too.

A caveat is that Mullvad assigns me a random port number. Let's assume it's 50000 in this guide. I first disabled the port-forwarding on my firewall for port 80 and 443, as they are unnecessary now. I thought I need to enable port-forwarding for port 50000, but somehow it worked without me doing so. The new port did require me to change the `listen 443 ssl` in `hideout-demo.com.conf` to `listen 50000 ssl`. Below is the final config. Notice the commented block at the end too.
