As in my previous query ref mobile connections
I have an RUT956 with latest firmware, running a Modbus RTU slave, Data to Server connects via RJ45/Wireless no problem. But it simply will not connect via Mobile.
I have reset to factory defaults numerous times, I have purchased new data SIMs, I have I believe, tried all avenues.
The unit shows it is fully connected with a good signal, the system log files show as connecting without any issues BUT it will not send any data, neither will it ping out from command line, neither will it connect to Teltonika RMS. In the system log it
I have tried all connection types (3g+4g - 4g(LTE) only, etc), I have reset the Bridge, removed all firewall settings, tried numerous configurations - then reset to factory defaults and started again from set up wizard.
I accept it may be something simple but I cannot find it.
It is effectively a useless brick at the moment.
Troubleshoot file is attached
