How to Allow Droppy to Work Over an HTTPS Connection

Have you already installed Droppy using docker on your Synology NAS following my step by step guide? Do you want to log in via HTTPS using your custom domain name even when you are away from home? It’s simple and free. You don’t need to buy domains, you don’t need to look for information elsewhere because here you will find the easy way to do it. Say you’re at a friend’s house and want to use Droppy. You can access Droppy from outside your home, just like you would any website.

Note: The guide below is deprecated – Check the new guide here: How to Run Docker Containers Over HTTPS

STEP 1

Go to Control Panel / Application Portal / Reverse Proxy. Click on Create. Follow the instructions in the image below.

STEP 2

The window below will open. Follow the instructions in the image below.

1 (Screenshot 1) On General TAB set the Reverse Proxy Description and type in Droppy. After that, add the following instructions:

Source:
Protocol: HTTPS
Hostname: yourname.synology.me
Port: 9090

Check Enable HTTP/2

Destination:
Protocol: HTTP
Hostname: localhost
Port: 8989

2 (Screenshot 2) On Custom Header TAB click Create then WebSocket.
3 (Screenshot 3) After you click WebSocket, the rules will be created automatically. Click OK.

STEP 3

Go to Control Panel / Security / Certificate and check if your link yourname.synologyme:9090 is visible.

STEP 4

Log into your router and go to the Port Forwarding area. Select your NAS Local IP Address and port forward port 9090 both TCP/UDP. Remember that every router has its own interface design. At the moment I am using a TP-Link router. Follow the instructions in the image below:

STEP 5

Open your browser and type in https://yourname.synology.me:9090 and you will see the HTTPS / SSL certificate working correctly. From now on you can access your Droppy application over HTTPS from anywhere.
