TLS issues can feel like a silent storm. Services slow. Connections fail. Security warnings rise like dark clouds. Today’s quick tip will help you cut through that noise and stabilize your Lansweeper server with clear, confident steps.
What is going on
Some Lansweeper users run into errors when their server is not using the right TLS settings. Scans may fail. The web console may refuse secure connections. Integrations that depend on modern encryption may stop working. The root problem often lies in outdated or disabled TLS protocols on the Windows server hosting Lansweeper.
TLS controls how your server encrypts data. Older versions, such as TLS 1.0 and TLS 1.1, are no longer secure. Many services no longer accept them. Lansweeper and its integrations expect TLS 1.2 to be active. If TLS 1.2 is disabled or not configured correctly, your server may fall back to older protocols or fail to negotiate encryption at all. Windows does not always enable TLS 1.2 by default, especially on older systems. That mismatch triggers connection problems.
How can I fix this
You can check and correct your TLS settings with IIS Crypto, a free and trusted tool from Nartac.
Follow these steps:
- Download IIS Crypto from https://www.nartac.com/Products/IISCrypto
- Run the tool on your Lansweeper server.
- Click the Best Practices button. This applies a clean, modern baseline.
- eview the list to confirm TLS 1.2 is enabled for both Client and Server.
- Click Apply.
- Reboot the server to activate the changes.
The reboot is mandatory. Without it, the new TLS configuration will not load, and the issue will persist.
Once the server restarts, Lansweeper should communicate using strong, stable encryption. Scans regain their rhythm. Integrations work again. The web console loads securely.
This quick fix takes only minutes but restores smooth, dependable operation. It also strengthens your security posture with modern TLS standards.
