Change off (Replaycing) Sonoff ZBridge to Sonoff Zigbee Bridge Pro

i have changed my Sonoff ZigBee Bridge to an Sonoff Zigbee Bridge Pro. Now i want to Connect the Pro to Home Assistant and it does not work. All the time i configured the Pro into “ZigBee Home Automation”, i get the answer: “Unknown error occured”. I do not know what i can do…, Have anyone an idea for the solution?
