The reason for receiving an error message regarding a failed connection attempt to (management.azure.com:443) when using a VNet integrated FunctionApp could be due to several reasons, including:
Virtual Network misconfiguration: If the VNet is not configured correctly, it can cause connectivity issues with other services, including management.azure.com.
Firewall settings: The firewall settings on the VNet or subnet where the FunctionApp is deployed may be blocking the outbound traffic to management.azure.com.
Network Security Group (NSG) settings: The NSG associated with the VNet or subnet where the FunctionApp is deployed may be blocking outbound traffic to management.azure.com.
DNS resolution issues: If the FunctionApp is unable to resolve the DNS name for management.azure.com, it will fail to establish a connection.
Outdated Azure PowerShell modules: The outdated Azure PowerShell modules installed on the FunctionApp can cause issues with the API requests to management.azure.com.
Subscription permissions: The user account used to authenticate the FunctionApp may not have sufficient permissions to access the resources on the management.azure.com endpoint.
