Hello Tom, and welcome to our community!
I’ve merged your topics as they are dedicated to the same issue you are experiencing with your RBOOM. Thank you for the troubleshooting you’ve already performed.
Could I please ask you to download the logs from the unit and post them (the instructions to do so can be found here: Please read before posting! ? They could provide more details on what is going on and I may be able to offer a solution to the current problem.
Thank you!
