Long delay from send MQTT command to Nuki 4.0 PRO

Do you have any idea what I could check to solve the problem?

Yes this is an already well-known Issue:

SL4P MQTT Problems since Nuki FW Update 4.1.8

Can you explain this a bit more please? In this|my Thread various problems I had where discussed and also fixed all the time. (From my side there is, BTW, only one last minor problem existing: Sometimes there is a delay of handling MQTT LockActions, which a) can be seen in an traffic capture and seems to be related with the MQTT KeepAlive process and b) is also already under investigation by Nuki)
