STM32WB55 Bluetooth Connection Issues

Hello everyone,

 

I have a problem with Nucleo-STM32WB55RG. I am trying to make an OTA Firmware application but for starting I am trying to make bluetooth application. I'm trying to reboot it using ST BLE Toolbox and it works good. But when I add 2 more service and 5 more charachteristic in total it stops working. Actually sometimes it is working sometimes it is not and when I connected it after 40 seconds it disconnects randomly. Can anyone inform me about these situation if anyone knows how to fix it. You can see my ioc in attachements.
