'Azure Web App Code 503 - Service Unavailable

I'm having a problem with my 4 webapps on Azure. All of them have "Running" status, but I cannot deploy new releases, I receive code 503 "Service Unavailable", the deploy does not complete.

My Apps run successfully on Visual Studio, I was inspecting the available logs on Azure and found this:

"[BYOS] Custom storage volume(s) failed to initialize: [/var/LWASFiles/Sites/webapp-name/a3cxxc4-116b-4ed3-9498-1fdddxxx13]".

Several days back, I do have an Azure App Service running a custom container and stopped working after binding the path to Azure File Share and observer this issue at the Container Issues Logs -

[BYOS] Custom storage volume(s) failed to initialize: [/var/LWASFiles/Sites/krishwebapp1205/d7126143-13k8-36b2-907c-0345718gxv71].

I resolved by enabling the storage account networking part to all networks in the portal.
