We are using a self-hosted agent on a Azure Virtual Machine Scaleset (VMSS) with Ubuntu 20.04 LTS and docker installed.

Deployment target is a static web app with a private endpoint. The VMSS instance has access to the VNET containing the static web app.

The error occurs constantly since 21/07/2023.
