When you link a Lansweeper Classic installation to a Lansweeper Platform site, one of the prerequisite checks confirms that your sync server can reach the internet. This page explains the check and how to resolve it if it fails.
Your sync server is the scanning server you select to sync with Lansweeper Platform.
Why this check runs
Lansweeper Platform is hosted in the cloud, so your sync server must reach it over the internet to link and stay in sync. Specifically, the sync server needs outbound access to the URLs below and their sub-URLs.
Allow traffic to these URLs on port 443, based on where your site is hosted.
| Europe | United States |
|---|---|
edge.eu.lansweeper.com |
edge.us.lansweeper.com |
https://id.eu.lansweeper.com |
https://id.us.lansweeper.com |
https://eu.lansweeper.com |
https://us.lansweeper.com |
https://discovery-gateway.lansweeper.com |
https://discovery-gateway.lansweeper.com |
*.aws.amazon.com |
*.aws.amazon.com |
*.amazonaws.com |
*.amazonaws.com |

The first time you create a US-based site from the Lansweeper Classic console, also allow https://eu.lansweeper.com while you create the site. The site doesn't exist on the US endpoints yet, so this initial call routes through the global endpoint. Once the site is created, you can remove this URL from your allowlist.
Syncing with Lansweeper Platform sends an almost constant stream of data between your sync server and the cloud. Lansweeper only allows syncing through HTTP/2-enabled proxies. If your installation uses a proxy for outbound traffic, enable HTTP/2 or add an exception that bypasses the proxy for edge.eu.lansweeper.com or edge.us.lansweeper.com, depending on your region.
Resolve a failed check
If the sync server internet access check fails, confirm your sync server can make outbound connections to the URLs above and their sub-URLs.
If it can't, ask your network admin to check the anti-virus software, proxy servers, software firewalls, hardware firewalls, and other components on your network. Any of these can block the sync server's outbound access.
When all prerequisites pass, you can link your installation to a site.
