Issue: Photon Client disconnect on websocket

I'm developing an online poker game using the Photon server/client with Unity 3d.

However, for no particular reason, the client has a disconnect and the cause is unknown, so I ask for help.

Client: Android, Unity 3d(5.6.6)
(Unity 3d adb Debug log) Client error:
