I could need some advice with the following issue:
We are using the RUT955 to build up a connection via APN to Tele2 with a triple SIM. In the LAN is a setup of multiple devices in form of charging stations for emobility which are connecting to our backend URL. Unfortunately we are experiencing repeating issues in which the router loses the connection to the APN. In the spotlight of Tele2 I see an abnormal release followed by 4 hours of trying to reconnect with timout and authentication problems and finally stopps trying to etablish a seesion to the APN. I need to send a reboot body via SMS to get the router building up a succesfull connection again. There is no authentication used for the APN. Is there any known issue about that. Are there any helpful options in the setup to influence this behavior? The issue occurs at multiple sites. Connections by the GSM-modems of the stations without the router are always stable.
Thanks for your support!
