The charger may show “offline” when it loses communication with the system.
What site owners and operators can check, by connection type:
SIM: the charger may have lost its cellular connection. This often recovers on its own within 15 to 30 minutes.
Ethernet:
Check that the modem or router is on and connected. Restarting the modem or router may help.
If communication is not restored, ask your IT department to check whether a firewall is blocking the charger's communication.
Wi-Fi:
The charger may have lost the Wi-Fi connection. Make sure there are no walls or obstructions between the router and the charger.
Restart the router.
Do not open the electrical cabinet or switch breakers yourself. Any work on the electrical installation must be done by a qualified electrician.
If the charger stays offline, contact support with the charger ID and the time it went offline.
Drivers: if a charger shows offline, use another charger if one is available and contact the site operator or support with the charger ID.
