Alarm Add-On board keeps rebooting

Board keeps rebooting when viewing status in Smartthings app. Uptime shows a few seconds each time I view the status. Contact sensors are no longer working. Flashed to 2.2.7 firmware but that made no difference. Worked fine until last few days. WiFi is at 100%. No issues with main alarm board. Any ideas what could be wrong?

Well, I did a flash again but this time with an erase. After WiFi rediscovery and syncing with SmartThings it resolved the issue. Hope this helps others.
