Hello,
I am trying to build a connector in dataminer and using HTTP request to call an API. But the dataminer is showing Handshake failure with TLS cert issue. Wile if I use Postman, there is no TLS error. I am attaching wireshark capture for both dataminer and postman for your reference.

As this question has now been inactive for a very long time, I will close it. If you still want more information about this, could you post a new question?
Hi Aditiben, the difference between Postman and DataMiner seems to be the TLS version that is being used for the request. Postman uses TLS 1.3, while Dataminer tries to connect using TLS1.2 and TLS1.1. The device you are trying to communicate with probably only supports TLS1.3? Maybe check if TLS1.2 can also be enabled.
The default TLS version that DataMiner uses depends on the server configuration and Windows version on which DataMiner is running as described here.
This page provides an overview of the TLS version per Windows version. On that page the following note can be found:
TLS 1.3 is supported starting in Windows 11 and Windows Server 2022. Enabling TLS 1.3 on earlier versions of Windows is not a safe system configuration.
If you still want to enable TLS 1.3 on an earlier Windows version, you can have a look this answer: https://community.dataminer.services/question/which-version-of-winhttp-and-ssl-tls-is-used-by-default/answer/43699/
I see that this question has been inactive for some time. Do you still need more information for this? If not, could you select Tom’s answer to indicate that the question is resolved?
