Just a cross post from the Teltonika website – users of the (excellent, btw) Teltonika RMS / Remote Management Service should be aware of port & IP changes that begin on 19th June 2023:

The additional IPs will not affect users who have defined rms.teltonika-networks.com as the server, because DNS will handle the IP changes. However RMS users may need to ensure the additional ports can reach the web.
