hi @Ramrunner
yes this is exactly the same issue I am having see here RMS connection failure to connect to registered new device
I’m not sure what the resolution is. from my experience, the ‘error’ that I got was exactly the same some times and other had different statuses. either way was just some part of the pipeline of connection not working at all.
today I will try the troubleshooting that teltonika has given below. and let people know wh at works or not
