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 am using Simba ODBC driver (32-bit) to query data from Google Big Query using C#. I keep getting the below error one or two times per week. Please help as I am not sure how to resolve this error.
ERROR [HY000] [Simba][DriverSupport] (1160) Cannot enable SSL for the
connection when connecting to a server that has not enabled SSL. If
the server has SSL enabled, please check if it has been configured to
use a SSL protocol version that is lower than what is allowed for the
connection. The minimum SSL protocol version allowed for the
connection is: TLS 1.1.
I'm trying to connect to DB2 db but getting the error:
DAL01013. Cannot create connection to server 'Unknown server' due to the following: [jcc][t4][2034][11148][3.69.24] Execution failed due to a distribution protocol error that caused deallocation of the conversation.
A DRDA Data Stream Syntax Error was detected. Reason: 0x3. ERRORCODE=-4499, SQLSTATE=58009
Assume it's something with my system. I cannot connect neither via DataStudio nor via QMF. Other users from other system can. I use same jdbc drivers. My system is Windows 7.
Is there anything else I need to adjust on my system?
Personal repository needs to be created first:
https://developer.ibm.com/answers/questions/470013/error-when-trying-to-connect-to-db2-vis-qmf/
Generally you get the reason 0x3 from error -4499 out of the IBM JDBC driver when you are connecting to a SSL port, but you have not specified sslConnection=true on your JDBC connection string. You can also get the error if your database name is incorrect (i.e. does not exist on the server), or your JDBC dirver is too old (DB2 JDBC Driver Versions and Downloads Download Fix Packs by version for IBM Data Server Client Packages)
If connecting to Db2 on Cloud, Db2 Warehouse or Db2 Warehouse on Cloud, all you should need is the sslConnection=true as the CA certificate used in these products is part of the Db2 driver package (for recent drivers anyway)
If connecting to Db2 on premise, you can specify your certificate location via the JDBC properties sslCertLocation or sslTrustStoreLocation and sslTrustStorePassword
Common IBM Data Server Driver for JDBC and SQLJ properties for all supported database products
sslCertLocation
Specifies that an application can configure the location of a trusted certificate file. For applications that have the database server certificate, sslCertLocation is the only property that is needed to be configured to instruct IBM Data Server Driver for JDBC and SQLJ to trust the certificate for SSL connections.
This property removes the need to import the certificate into a Java truststore database and related driver configurations.
Error codes issued by the IBM Data Server Driver for JDBC and SQLJ
error codes in the ranges -4200 to -4299, and -4450 to -4499 are reserved for the IBM® Data Server Driver for JDBC and SQLJ.
I have my Data in a DB2 hosted in a VM which has the port with SSL enabled 50444. When I use Power BI Desktop to connect to DB2 DB using Microsoft driver , I get this error:
DB2 DBA has given me CACERTS (ARM file), which I used the Keystore command and updated my Java JRE folder. Not sure what else to be done or if Microsoft has different folder to update the SSL certificate etc..
Can someone help me to resolve, if you had faced a similar issue.
Thanks
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
