EVNEX charger
He will need to set his OCPPEndPoint to wss://192.168.1.22:9000. The port setting is no longer used. He will also need to setup basic auth on his server.
If he uses ws://192.168.1.22:9000, then there will be no encryption and can use a tool like Wireshark on the server end to see the connection being established and any failure response.
Again, the first most important thing is that the charger has a working network connection.
I assume that it is on WiFi or Ethernet given that the OCPPEndPoint IP address is local. The blue light should be flashing fast (about twice a second).
