Common causes of Azure VM connectivity issues
There are several factors that can cause connectivity issues with Azure VMs. Some common causes include:
- Network security group (NSG) rules: NSG rules allow or deny traffic to and from a VM. If the NSG rules are not configured correctly, it can cause connectivity issues.
- Virtual network (VNet) configuration: VNet configuration issues, such as incorrect subnet configurations or incorrect VNet peering, can cause connectivity issues.
- Public IP address (PIP) configuration: If the PIP is not configured correctly, it can cause connectivity issues.
- Operating system (OS) firewall: The OS firewall on the VM can block incoming or outgoing traffic, causing connectivity issues.
