Azure Backup Fails

Hello –

Working on setting up backup to Azure with v3.5.0 on WP v4.9.5.

Backup job works fine until it comes time to upload:

[16-May-2018 20:15:42] 1. Try sending backup to a Microsoft Azure (Blob) …
[16-May-2018 20:15:42] Connected to MS Azure container “wpbackup”.
[16-May-2018 20:15:42] Starting upload to MS Azure …

Any ideas on this?

Thanks.
