Hi,
We are running an SQL server 2008 that we used to connect to with an On-premise gateway. One day the connection stopped working with SSL error, claiming that the certificate had expired. When I try to connect to the instance with SQL manager 2017 using Windows Active directory(Integrated) I get the error too, SSL certificate has expired.
The thing is that SSL isn't enabled on the SQL instance. In fact, I don't even see the Certificate tab in SQL Configuration.. SQL Server runs as Network Service. We have a PKI, ADCA, and machine certificates are autoenrolled, and not expired.
What has happened? Why can't I activate SSL on the server and why do we get SSL errors though it isn't even activated?
