[Bug]: Cannot create networks using Container Manager

[amine-aboufirass]

Operating system

Windows 11

Description

I'm currently working attempting to deploy a Docker Compose application in VDSM using container manager for testing purposes. It seems that adding a network using SSH and/or the Synology UI causes VDSM to hang and eventually fail. I'm observing this behavior on clean Docker Compose installation of VDSM with Container Manager.

Is there something weird going on with VDSM here or is this perhaps a bug in Container Manager? I'm trying to pinpoint the issue so as to avoid it happening in our production environment.

Thanks!
