When the DC (Data Center) connection status = 3, it means the DC is offline and cannot access the internet.
If the Ethernet cable is confirmed to be plugged in and working properly, the most common cause is that the home router has blocked the DC device.
This usually happens in the following cases:
- The router has ACL rules (e.g., IP/MAC binding + auto-blacklist for violations).
- The user’s network is part of a corporate network with NAC/IDS enabled, which may classify Yarbo DC’s outbound traffic as unauthorized and block it.
- In most situations, this is not accidental — users (or IT administrators) have configured such rules knowingly.
Use a computer or smartphone and connect it to the same Wi-Fi as the DC.
- Open a browser (Chrome, Safari, Edge).
- Enter the router login address (usually printed on the router label or manual).
- Enter the admin username and password.
- By default, this is printed on the bottom of the router unless changed.
- Navigate to Device Management / Access Control / MAC Filtering (name depends on router).
- Look for blocked or blacklisted devices.
- Identify the DC by its MAC address or device name.
- Select it and click Delete / Allow Internet Access.
- Save changes and restart the router if necessary.
- Once unblocked, check if the DC status changes from 3 (offline) to online.
- If the issue persists, escalate to Yarbo Support for further assistance.
- Interface names vary by router brand.
- If the user cannot find the setting, they should contact their Internet Provider or IT Admin for help.
Important: Placing DC in a corporate network with NAC/IDS is not recommended, as this may repeatedly block Yarbo’s DC connection.
