Router RB433 restarting at every 2-3 minutes

Please, what can I do my router is restarting every 2-3 minutes.

Have you a radio card attached if yes plug it out and see if the 433 will stay on or restart?

Thanks, No radio card on it.

Have you checked the logs, tried another power supply, or reflashed the 433

Thanks, once again. I powered it through POE, but I have changed to direct power through its adapter. I’m still observing it.
Thanks.
