My Synology NAS allows the use of SSL to encrypt traffic. The default certificate supplied works, but gives an exception in the browser: There is a problem with this websites security certificate. The problem is the address and the certificate don’t add up. So the solution is to setup your own domain, link it to your NAS and create a certificate for it.

Monitor your domain
Checking your domain is up-and-running is as simple as typing the url in any browser. But why do this yourself every 5 minutes when online tools can do this for you.
This post lists some free uptime monitoring web applications. I picked uptime robot for my sites. It is still free 
and offers up to 50 monitors of websites, ports, pings and keywords. Whenever there is no response you can get notified by e-mail, push, rss, twitter or sms. When the site is back up, you’ll get notified again.
On the My Monitors tab you see the current state of the monitors and the uptime in percentages. I added the monitors after the first post, that is why the uptime is not 100%. 
The alerts go to my freshdesk e-mail address and are processed there. More about freshdesk in a future post.
Note that the used domain FINDMYNAS.NL is not mine and only used for demo purposes because it was available at the time I created this post.

Hi, had the same problem. But thanks to your article, I now finally solved it. Thanks a lot!
Eric – Thanks so much for taking the time. I’m glad to say that this blog saved me and it was 3.5 years after you wrote it! It took some time as the GUI’s changed over the years but I managed to figure it out. There were a lot of ‘fragmented’ posts but nothing that took me from start to finish. Cheers! Glenn
