What websites does my Synology NAS connect to when running services or updating software?
Details
Synology has set up various websites to increase the stability of services on your Synology NAS. When running services or performing software/package updates, your NAS connects to the respective websites. To allow access through ports 80 and 443, make sure all the URLs listed for the packages/services are allowed in your firewall rules.

Notes:
- Since DSM 7.2, Container Manager has replaced Docker for container management.
- If you have specified a custom registry URL in Registry > Settings > Add or a mirror URL (e.g.,
https://dockerproxy.com
) in Registry > Settings > Docker Hub > Edit > Enable registry mirror, make sure your Synology NAS can reach the URL. - Offline activation is not available. To activate Presto File Server or add a license for the first time, make sure your Synology NAS and computer both have HTTPS (port 443) access to the listed websites.
- The purpose of the website is to identify the geolocation of the photos and display the location name in the service.
