Some users have reported the following error at connect:

Message: The server selected protocol version TLS11 is not accepted by client preferences [TLS13, TLS12]

Starting in Java 11 (used by DbVisualizer 12+), TLSv1 and TLSv1.1 are outdated and disabled. For servers still require these versions, you need to re-enable these. 

Option 1 - Create an overridden file (preferred)

First, open C:\Program Files\DbVisualizer\jre\conf\security\ (Windows) in a text editor and locate security.overridePropertiesFile. Set its value to true (this is usually the default value). Then, take the following steps:

  1. Create a file named
  2. In that file, add an entry for jdk.tls.disabledAlgorithms with the same contents as the jdk.tls.disabledAlgorithms property in the file
  3. Remove TLSv1 and/or TLSv1.1 from the list in the file
  4. In DbVisualizer open Tools->Tool Properties and select the General tab. In Specify Overridden Java Properties here text box add a new row with:
  5. Click OK, restart, and then connect.

Option 2 - Update the Java installation

Update the file that is included in the Java installation. For bundled Java this file is typically available in C:\Program Files\DbVisualizer\jre\conf\security\ in Windows.

Open the file in a text editor and locate jdk.tls.disabledAlgorithms:

jdk.tls.disabledAlgorithms=SSLv3, TLSv1, TLSv1.1, RC4, DES, MD5withRSA, \

Remove TLSv1.1 from the list of algorithms:

jdk.tls.disabledAlgorithms=SSLv3, TLSv1, RC4, DES, MD5withRSA, \

Save the file and connect.

A better option than enabling outdated SSL versions is to ensure the server is using the latest recommended versions.
