Spanking brand-new installations of:

  • Visual Studio 2022 Community (VS)
  • SQL Server 2019 Dev (SQL)
  • SQL Server Management Studio v18.10 (SSMS)

There are no other Visual Studio or SQL Server instances or installations.

I can look at my local SQL instance using SSMS but not SQL Server Profiler. I am using Server Name "." and Windows Authentication in both cases. Profiler is being launched both in SSMS and directly launched (in administrative mode or not), with the same results: SSL Provider: The certificate chain was issued by an authority that is not trusted.

SQL-related services are in these states (enabling SQL Server Browser has no effect):

"Trust server certificate" does not help. I suspect the provider is extremely sloppy about the root cause of this response.

(Same system environment as https://stackoverflow.com/posts/70805318/)

  • Not that this is necessarily related to your issue, but do you mean you installed SSMS v18 (15 being the build number)?...otherwise SSMS v15 would be a very old version.

  • Also, could you post a screenshot of which SQL Server services are currently running? (You could find this if you run the SQL Server Configuration Manager.) Also what happens if you try using localhost as the server name?

    The component name is SQL Server Management Studio: 15.0.18390.0. But yes, it says v18.10. Go figure. Commented Feb 5, 2022 at 18:04

A quick fix is to disable cert verification for the connection by selecting the connection option "Trust the Server Certificate":

  • Check the SQL Log and the Connectivity Ring Buffer: github.com/microsoft/CSS_SQL_Networking_Tools/wiki/… Commented Feb 5, 2022 at 19:42
  • The log has: Date,Source,Severity,Message,Category,Event,User,Computer 02/05/2022 12:14:51,Schannel,Error,The certificate received from the remote server was issued by an untrusted certificate authority. Because of this<c/> none of the data contained in the certificate can be validated. The TLS connection request has failed. The attached data contains the server certificate.<nl/> The SSPI client process is PROFILER (PID: 29064).,(0),36882,xxx\yyy,xxx It would be nice if I could find the "attached data" :-) Commented Feb 5, 2022 at 20:23
  • The "ring buffer" has two records: ConnectionClose and LoginTimers with error 17830 - no joy there (bobsql.com/sql-mysteries-why-am-i-still-seeing-17830-errors/…) Commented Feb 5, 2022 at 23:14
  • I see exactly that behavior if I try to connect using an encrypted connection where SQL uses a self-signed certificate without selecting "trust server certificate". Perhaps you can use a trusted certificate, or allow unencrypted connections. Commented Feb 5, 2022 at 23:31
