VM Cloud is secured by IP security, which locks access to your system based on the public IP address of your property's Ethernet network. This ensures that only users within your hotel network can access your data, unless explicitly permitted. The public IP is provided by your Internet Service Provider (ISP), and each ISP assigns a unique public IP to each user. Additionally, your Ethernet network and Wi-Fi will have different public IP addresses.
The most common scenario for this issue is when a property changes its ISP, resulting in a change of the public IP address. Since VM Cloud is locked to the previous IP, any user without remote access will be locked out.
To allow VM Cloud to recognize the new public IP, simply restart your broker service.
