Whitelist URLs for license validation

[Obi_1_Cinobi]

1. Server Connectivity

Both the Lansweeper Sync Server and the Lansweeper Web Server must be able to establish a secure outbound connection to the Lansweeper cloud platform.

• Only one Sync Server exists per on-prem installation
• If multiple scan servers are present, one is designated as the Sync Server

2. TLS 1.2 Configuration

TLS 1.2 must be fully enabled on:

• Lansweeper Sync Server
• Lansweeper Web Server

Recommended Validation Tool

You can verify and enable TLS 1.2 using the free IIS Crypto tool: https://www.nartac.com/Products/IISCrypto

Steps:

1. Run IIS Crypto as Administrator
2. Click Best Practices
3. Click Apply
4. Reboot the server to apply changes

3. Whitelist Required URLs

Ensure the following URLs are allowed in any firewall, proxy, or network security software:

https://edge.lansweeper.com
https://id.lansweeper.com
https://app.lansweeper.com
https://installerapi.lansweeper.com
https://login.lansweeper.com
https://lansweeper.azure-api.net/
https://lansweeper.azure-api.net/ls-instances/activationurl

Failure to allow these endpoints may result in license activation issues.
