# Bug Report

### Describe the Bug
Bridge service stops almost as soon as it starts - seems to be caused by a duplicate address issue per the log

### To Reproduce
Every time I restart or reboot the service only runs for less than a minute before stopping 

### Expected behavior
I would expect the bridge service to be stable and continue to run

Note: I truncated cached accessory references and replaced serial numbers with XXXXX - let me know if either of these elements is required.
### Additional context
<!-- ✍️edit: --> Add any other context about the problem here.
I updated the plugin last night and again this morning - I believe I was having the issue since at least last night, but maybe longer (it was 9.1.1 before I updated)
