After updating the SpanVA to version 1.15.3.167 the SpanVA was unable to perform a backup.
A new install of SpanVA 1.15.3.167 is able to perform a backup.
Resolution
2 dependencies fail to deploy while updating to the SpanVA. A new SpanVA update version 1.15.3.168 is tentatively planned for the first part of October 2025.
It is possible to update the dependencies with a remote session by opening a support ticket.
Additional Information
New SpanVA deployments of version 3.167 do not have this issue.
