When I try to use VictronConnect desktop app to remotely configure my Victron Smart Solar MPPT's, I keep getting this error: "MQTT-RPC Unable to connect to RPC broker. Configuring the device is not possible. Error Code #R6". Please what is the cause and solution to this problem?
Try to enable MQTT on the GX device and reboot it.
Also try to restart the VictronConnect app.
I've been able to get the VC-R to work on my phone. Not yet on my laptop. I put on the two MTTQ's and after that it worked on my phone. When I later had problem with my Cerbo Connection to WiFi, I switched OFF the two MTTQ's. VC-R still working on my phone. Working even with VC-R open on two phones. Will try again on laptop when I have time.
