Invalid id on Android App

My Camera is C34S-X4, after setup and use for 1 week. I can not connect to Camera.
I had to power off-on. After restart the camera, things seem ok. But after some hour, i can not connect to camera again.

When i try to connect on Android it shown me "invalid id".  I have to power off-on again. Then everything work!.

Any suggestion?
