Have you already installed YouTube Downloader 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 Youtube Downloader. You can access Youtube Downloader 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

Please Support My work by Making a Donation.

• STEP 2

Follow my step by step guide on how to activate your synology.me DDNS on DSM 7
Follow my step by step guide on how to activate your synology.me DDNS on DSM 6.2.4
Note: If you already own a synology.me DDNS, skip this STEP.

• STEP 3

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

• STEP 4

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

On General area set the Reverse Proxy Description and type in Youtube Downloader. After that, add the following instructions:

Source:
Protocol: HTTPS
Hostname: yourname.synology.me
Port: 8085

Check Enable HTTP/2

Destination:
Protocol: HTTP
Hostname: localhost
Port: 8084

• STEP 5

Go to Control Panel / Security / Certificate and check if your link yourname.synologyme:8085 is visible.

• STEP 6

Log into your router and go to the Port Forwarding area. Select your NAS Local IP Address and port forward port 8085 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 7

🟢Please Support My work by Making a Donation. Almost 99,9% of the people that install something using my guides forget to support my work, or just ignore STEP 1. I’ve been very honest about this aspect of my work since the beginning: I don’t run any ADS, I don’t require subscriptions, paid or otherwise, I don’t collect IPs, emails, and I don’t have any referral links from Amazon or other merchants. I also don’t have any POP-UPs or COOKIES. I have repeatedly been told over the years how much I have contributed to the community. It’s something I love doing and have been honest about my passion since the beginning. But I also Need The Community to Support me Back to be able to continue doing this work.

• STEP 8

Open your browser and type in https://yourname.synology.me:8085 and you will see the HTTPS / SSL certificate working correctly. From now on you can access your Youtube Downloader application over HTTPS from anywhere.

Note: If you don’t like to see port :8085 at the end of your link take a look at my new article HTTPS-SSL to Your Docker Containers Without Port at The End

Note: You can use the same operation described above for all docker packages you have previously installed on your Synology NAS to access them via HTTPS/SSL.
Note: At STEP 4, instead of port 8085 you can use the port of your choice, but remember to port forward it (correctly) in your router following STEP 6.
