Hi, Please can you check the following by directly accessing (as remote access is not working) the device web interface ?
1> Make sure you're on the default factory settings and your DNS address hasn't been changed.
2> Make sure the port for rms.teltonika.lt is 15009
3> Check default WAN set as an active interface which also resolves DNS correctly. If there's something in the gateway blocking the address - it also might cause this issue. Please try setting the mobile interface as your main WAN and check.
4> The RMS service can be accessible via 18.196.62.30 IP address. It can be specified in the System -> Administration -> RMS WebUI page.
4> From the device CLI please capture the output of netstat ‐n ‐p ‐t, also run the following command "traceroute rms.teltonika.lt"
5> Please share the troubleshoot file from the device webui as follows : (System -> Administration -> Troubleshoot)
Thanks
