Error code 520 implies Connection Timeout indicating link supervision timeout or syncronization timeout. Is this issue seen with only one device ? Can you switch the phone to some other device and check ?

What happens if you use nimble's bleprph/ blecent example, do they work ?

I have changed both the controller and phone it does not work. Same issue comes in bleprph and blecent example.
Only Bluedroid_GATT_Server works correctly.
