  • A connection refuse message will most likely mean that either the address and port you are connecting to is being blocked or filtered for whatever reason, or nothing is running on the specified address and port. – Aval Sarri Aug 19 '21 at 11:45
  • How can I fix it ? – Takwa Aug 19 '21 at 20:27

I got the same problem. Base on Takwa answer I had already solved this problem. The property file path is {Apache Directory Studio Home}/ApacheDirectoryStudio.ini

In this file disable -vm mark and add java.exe. And I also found that, not all version after Java 11 JDK can work. In my case I first try JDK 17 will occur this error. After I edit the property file and set the JDK version 11 this error will not happend.

My property example My property example

The problem was in the jvm I install the jdk 11 and I open the configuration file of apache directory studio to add vm and the local path of jdk folder and I add this \javaw.exe

-vm
E:\Repositories\Jdk11.0.12\bin\javaw.exe

I installed Apache DS on an EC2 instance, but the connection port was configured by default to 10389. After changing the port on Apache Studio it connected.
