LoRaWAN Gateway Connection Authenticated/Connection Ended Loop

We are experiencing issues with Multitech Conduit AP LoRaWAN gateways where they will, without any outside change, go into a loop where they constantly ask to connect, get authenticated and then disconnected a few seconds later. They stay in the loop state - sometimes permanently, sometimes connecting after many hours. We have been logging the issue on Cloudwatch and the infuriating thing about this issue is that a gateway will be stable for weeks, then suddenly go into this death spiral.

For context, all gateways are updated to version 6.x firmware and are using LTE connection. Sometimes a connectivity reset of the SIM connection will bring the gateway back, but not always.

Example from logs below.....anybody else had this issue and know what it might be?
