As a first time user of a RUT360, I configured succesfully the Teltonika OpenVPN connection.
After that, I tried to activate the WebUI and CLI to RUT360 from rms.teltonika-networks.com.
Then immediately lost this cloud connection my RUT360.
I found a partial solution: I changed in the RUT360 RMS cloud config page from the default rms.teltonika-networks.com setting to its IP address 22.214.171.124.
After router restart the RUT360 could to connect the 126.96.36.199 server, it went online, but the WebUI and the CLI interface were still left unreachable - in legacy mode also (in spite of these connections were enabled in RUT360 config site).
Please help me, because I have to give RUT360 back to my Teltonika partner.
Thanks in advance.
