When you start setting up a link with your Cloud site, some prerequisite checks are performed to ensure your installation is ready to link. When you hit the
Link with Cloud site button in your local web console, a popup is presented with a pass/fail indication for a number of prerequisite checks. One of the checks is whether your sync server has TLS 1.2 enabled.
Why is sync server TLS checked?
Your sync server is the machine selected to sync with Cloud. In order to secure the communication between your local Lansweeper installation and Cloud, Cloud is configured to use the TLS 1.2 cryptographic protocol. If your sync server does not also have this protocol enabled, communication with Cloud will fail as a result. Computers running a modern OS ordinarily have TLS 1.2 enabled by default.
What do I do if the sync server TLS check fails?
If the sync server TLS check fails in the prerequisite popup, make sure TLS 1.2 is in fact enabled on the machine hosting your sync server. Instructions for enabling TLS 1.2 can be found online and in Microsoft's knowledge base. Practice caution if you're editing TLS settings directly in the machine's registry, as incorrect changes may break the machine.
