Why does my charger not connect the OCPP platform?

Connection issues can be one of the hardest topics to troubleshoot. Here's some handy guidance on how you can troubleshoot a connection problem to an OCPP service on zappi:

Please use this checklist:

1. Please check your charge point is online in your myenergi myaccount. You should see the words 'Active' next to the zappi on the my products page
2. Try rebooting the charge point. You can do this by pressing the menu icon on zappi and holding then holding down the menu button down until the charge point restarts
3. The ChargeBoxID matches what you’ve entered into the platform you’ve chosen (Sometimes this will be referred to as an EVSE ID)
4. The username and ChargeBoxID match
5. If you were provided with an authorization key, please check it matches what the provider gave you and there is no whitespace (particularly at the end, if you’ve copied and pasted)
6. Go to the OCPP settings and check:
   • The URI matches what was given by your platform provider
   • The URI ends with a forwards slash (/)
   • If you have chosen the Other / Manual setup option and you’re using a Secure WebSocket Connection (starting WSS://) ask your provider if they have an unsecured WebSocket URI (starting WS://).

Whilst we don’t recommend using this for ongoing use, it can help us understand if there is a problem establishing a secure connection with the provider you have chosen.

If after step 6 your connection works, please let us know and we’ll try to reach out to the provider to solve the issue. To help us resolve this as quickly as possible for you please write a support ticket:
