Windows agents and probes have been updated to require TLS 1.2. SolarWinds N-central uses TLS 1.2 as a default configuration. This means that SolarWinds N-central does not allow traffic over TLS 1.0.
This causes any Windows agents or probes that are running on Windows XP and Windows Server 2003, as well as pre-v12.1 versions of the MacOS agent, to lose the ability to communicate with your SolarWinds N-central server.
You can switch the network security to use older TLS versions so you can continue to monitor these devices.
This setting is only available at the System level. Changing this option will require the server to be restarted.
- Click Administration > Mail and Network Settings > Network Security.
- Click the Legacy Settings option.
- Click Save.
- SolarWinds N-central will prompt you to acknowledge a reboot of the server.
The server is rebooted and begins using the TLS 1.0 and 1.1 security.
