I have installed Lince Bi on Windows machine but on connecting SQL server it is showing SSL error.
"com.microsoft.sqlserver.jdbc.SQLServerException: The driver could not establish a secure connection to SQL Server by using Secure Sockets Layer (SSL) encryption. Error: "No trusted certificate found". ClientConnectionId:92c4c4cd-5088-45d0-97c6-363303c25af1
"
I already added trust certificate
If the driver keeps failing with the encryption error, make sure to provide the "Encrypt=false" parameter to the data source.
You need to provide the apropriate Microsoft JDBC driver in order to LinceBI work correctly as well.
You can download it from Microsoft: Download Microsoft JDBC Driver for SQL Server
I use mssql-jdbc-10.2.1.jre8.jar because I'm using Java JDK 8.
The driver must be put inside the lincebi_web\tomcat\lib directory.
Best Regards!
I have been digging for answers for this issue and have not been able to solve it. I believe it is a TLS issue but nothing I've tried fixes it. Setup ...
The reporting application server trying to connect to the database server via ODBC SQL Server is using the SQLSRV32.DLL version 6. (I know the driver is old and updating would probably fix the issue but that is not so easy to do). I have confirmed on both hosts that TLS 1.0 is not enabled. I did this by checking the registry under "SCHANNEL->Protocols" and using "Internet Options -> Advanced Tab". Both only have TLS 1.1 and TLS 1.2 checked. The error is "Error 772; Connection Failed; SSL Security Error". I found a host with an updated ODBC driver (v10) and it can connect to the database.
I have another DB and reporting server with what appears to be identical configurations, using the same old SQL driver, but they are not having the issue. Trying to connect from this reporting server to the other database fails too.
I believe this is an issue with the database server, possibly SQL Server, but am stuck on what to look for.
Any guidance on what else to look at would be appreciated.
I'm suddenly having a problem connecting to my local instance of SQL Server 2005 Database engine. I had no problem connecting to this instance a few days ago. I can however connect to Integration Services and Analysis Services. Only the Database engine is giving me this error:
A connection was successfully established with the server,
but then an error occurred during the pre-login handshake.
(provider: SSL Provider, error: 0 -
The Local Security Authority cannot be contacted) (Microsoft SQL Server)
Only thing I did was I installed Visual Studio 2017.
This is a generic error that has many reasons. Usually is things like expired password. To troubleshoot, you should enable Netlogon service logging, follow Enabling debug logging for the Netlogon service:
c:\>Nltest /DBFlag:2080FFFF
Then reproduce your problem then look into the logging file, which is going to be located at %windir%\debug\netlogon.log. Read the file, try to understand what is happening.
Don't forget to turn off the debug logging afterwards:
c:\>Nltest /DBFlag:0
Within two environments, where database servers with SQL Server 2008 R2 and SQL server 2012 are operated, the Extended Protection and SSL Encryption settings have been enabled. Since then, the applications (SharePoint 2010, SharePoint 2013 und ADFS) are having problems connecting to the databases. Following error message is logged in the SQL Server error logs: “SSPI handshake failed with error code 0x80090346, state 46 while establishing a connection with integrated security; the connection has been closed. Reason: The Channel Bindings from this client are missing or do not match the established Transport Layer Security (TLS) Channel. The service might be under attack, or the data provider or client operating system might need to be upgraded to support Extended Protection. Closing the connection.”.
On the client-side, following error message is logged: “Login failed. The login is from an untrusted domain and cannot be used with Windows authentication.”
Basically, when both settings are enabled, the remote connection, even through SQL Server Management Studio, does not work anymore. This issue can be resolved by disabling one of the two settings.
If "disabling one of the two settings" still results in the connection between the two servers being encrypted, then your objective might have been achieved sufficiently by using only the other.
I suddenly started getting this error when trying to connect to any of my sql servers (25+) from SSMS on Windows XP. When I left work yesterday everything was working fine, came in this morning, and I started getting this. Tried rebooting my pc but that obviously didn't fix it. My co-workers can all connect just fine. Searched for a solution but everything I found was regarding encryption in regards to .NET applications. Not sure how to apply that to SSMS.

For some reason the image won't work so the error is this:
A connection was successfully established with the server, but then an error occurred during the pre-login handshake. (provider: SSL Provider, error: 0 - The certificate chain was issued by an authority that is not trusted.) (Microsoft SQL Server)
The question seems to have been answered, but I wanted to chime in. For some providers, such as SQL Server, there is a parameter in connection string which lets you connect to server encrypted even if certificate is unknown: "TrustServerCertificate=True", so if you include that in a connection string, you will connect and work encrypted, and will not have to run connection non-encrypted.
Try this...
Its gotta be a client issue if you lost connection to all your remote servers and your coworkers are fine. You probably got "clicky" and changed some settings inadvertantly.
Open your client network utility (mine is here: C:\WINDOWS\system32\cliconfg.exe).
Under the General Tab, check out the disabled protocols. They should all have "force protocol encryption" unchecked. If this is checked for any of those values, your local SSMS is probably trying to force an encrypted connection and failing.
Report back if this doesn't work, and I'll poke around a bit more.
When connecting using MS SQL Server Management Studio in the connect window go to Options->Connection Properties and check checkbox Trust server certificate
You connect to your SQL Servers requesting encrypted connections and you don't trust the certificate(s) used by those servers. Why that happens depends on a myriad or reasons.
Do your servers use self-signed certificates or PKI issued certificates?
Who is the PKI authorithy that issued your certificates? Is it a corporate certificate service?
Does your computer trust the PKI root authority?
If you don't know the answers to this, you must contact your network and security administrators. Simply disabling protocl enforcing requirement from your client may be against corporate policy, or the servers may enforce SSL anyway disregarding your local setting.
These are all questions you should ask your own environment admins, not public forums. You should try to solve the issue, not hack your way arround it and end up with a non-compliant machine.
From this link:
Disable client-side Force Encryption
on the server. On the machine that
runs the SQL Server instance, open up
the SQL Server Configuration Manager,
right-click SQL Native Client
Configuration, and set Force Protocol
Encryption to No. Then try connecting
locally.

I got this error, I tried to connect a remote server SQL (SaaS) in MS Cloud
I added a new firewall rule in Azure portal with my client IP that solved my issue
Open Command Prompt: press Windows Key+ R then type cmd and run
Enter this:
runas /user:[YourDomainName]\[YourActiveDirectoryUserName] /netonly cmd
Enter your active directory password and press enter
In New Command Window enter your SSMS.exe Path with double cotation like:
"C:\Program Files (x86)\Microsoft SQL Server\130\Tools\Binn\ManagementStudio\Ssms.exe"
Then login with windows athentication
