I'm running MSSQL 2017 on Server 2016 and monitoring it via CheckMK. I'm getting critical alerts that state:
Failed to connect to database (ERROR: [DBNETLIB][ConnectionOpen (SECCreateCredentials()).]SSL Security error. (SQLState: 08001/NativeError: 18))CRIT, Version: 14.0.1000.169 - Standard Edition
We have TLS 1.2 enabled and TLS 1.0 and 1.1 disabled.
Does anyone have any idea what this issue may be, and the fix for it? I thought maybe the Native Client was too old, but after further review I don't believe so.
