Hello,
I've encountered a specific issue on two of the HTTP requests. I'm getting ERROR_WINHTTP_SECURE_FAILURE error. I've read the other questions here but the strange issue is that there are other requests as well that go through, but its just a specific endpoints that result in this issue. I've tried hitting the endpoints via Postman and it worked as expected. Can this still be related to the licenses on the server or can it be DataMiner related? (I've investigated the code side of the requests and there is nothing unusual).
Thank you 🙂
DataMiner connectors that use HTTP connections rely on WinHTTP to handle requests, which delegates SSL/TLS handling to the operating system.
Which operating system version is your DataMiner running on?
It’s likely that the endpoint you’re trying to reach only supports TLS 1.3, while your OS doesn’t. You can verify this by inspecting the TLS handshake in a Wireshark capture. If TLS 1.3 is indeed required, check whether it can be enabled on your system.
