TestProject agent fails to upload test results and screenshots

This started since a month or two. Earlier test results would be uploaded correctly and were visible on the TestProject portal. But this has stopped working and I cannot see test results any more.

Logs from the agent hint at uploading to AWS failing due to bad signature.
