file upload failing in v1.14.0 using x509 authentication

[kaikeraut]

I have updated azure sdk from 1.11.0 to 1.14.0 and now file uploads are failing, telemetry data is successfully getting sent.

I am using DPS service, x509 certificated-based authentication for iot hub connection.

I am still using IoTHubDeviceClient_LL_UploadToBlob Api to upload data to blob as stated in below sample link which is working fine with older sdk too.
https://github.com/Azure/azure-iot-sdk-c/blob/main/iothub_client/samples/iothub_client_sample_upload_to_blob/iothub_client_sample_upload_to_blob.c

Here is Firmware error logs:

I am using esp32 board with esp-idf v.5.2.
I tried same certificates in windows Linux subsystem there also file upload fails
