TLS handshake works in Editor but not on HoloLens

Viewed 205

In our HoloLens project we have a feature that runs with Azure blob-storage.

The goal of this feature is to upload/download files from Azure.

Working with Unity 2020.3.19 (UWP-platform) and MRTK 2.7 the feature is running smoothly.

Updating to Unity 2020.3.25 the feature still works in Editor, but on HoloLens there the following error pops up:

TlsException: Handshake failed - error code: UNITYTLS_INTERNAL_ERROR, verify result: 4294950016

Apparently this is related to some certification issue, does anybody have the same experience or found a solution for this issue?

The issue comes from an Unity internal issue.

Here is the link to the Unity issue-tracker

The only way to prevent this issue for now is to downgrade the Unity version.
