Showing default status Preparing (Without gunconnect) and rejects RemoteStartTransaction

[demirschmid61]

Hello @matth-x,

I did 146 ocpp transactions for 147th transaction the RemoteStartTransaction gets rejected and the connector status shows Preparing without a gun connection. Please have a look at the logs

I reset the charger many times, even if it shows preparing and rejects the remoteStartTransaction request.

Can you please tell me where it went wrong, or is there anything I need to set or reset?

@matth-x There is a little update on this problem

I followed the process to crosscheck

1. Took esp32 which is giving the above problem
2. All the configurations were the same
3. Uploaded firmware which has matth-x/MicroOcpp@^1.0.0 version
4. Checked the status (Issue resolved)

Please have a look at the logs
