SSL certificate for Synolygy private NAS without a domain name?

@MikiloIX

After all that, though, if you’re on your home network and connect to your NAS, you will still get the warning page, because the SSL certificate will be for your domain, but your browser will be connecting to a local IP address instead of the domain associated with your certificate.

If the local IP address doesn't change over time, you could create a hosts file on your computer(s) pointing this name to the local IP address so that you could use the name and see the valid certificate from within the LAN (although this would then prevent you from accessing the NAS using your computer(s) when you're not on your LAN). There are lots of different solutions to this limitation, although they're all a bit more work.

Hi !

Thanks a lot for all your support!

Setting up DDNS I have thius error message on my Synology :

Failed to register IP address 109.133.160.192 to hostname willyandchiara.eu [Authentication failed.]

What do you think I did wrong?

Currently, willyandchiara.eu points to 188.165.53.185 in DNS, not 109.133.160.192. If your public IP address 109.133.160.192 was assigned by your ISP, you might not have your dynamic DNS client correctly configured to point the domain name to your address.

Schoen,
Thanks for the tip. This makes perfect sense for my home desktop.
