BraviaTV : rise the time out

Configuration
1

Hi,
my media_player.braviatv is switching from “on” to “off” (without any visible pattern) while the device is of course constantly on.
05

The only thing I see in the logs, is that there’s a time out getting /sony/audio

2018-07-23 10:51:24 WARNING (MainThread) [homeassistant.helpers.entity] Update of media_player.tele is taking over 10 seconds
2018-07-23 10:51:24 ERROR (SyncWorker_5) [braviarc.braviarc] Exception: HTTPConnectionPool(host='192.168.1.76', port=80): Max retries exceeded with url: /sony/audio (Caused by ConnectTimeoutError(<urllib3.connection.HTTPConnection object at 0x7f8d2072ab38>, 'Connection to 192.168.1.76 timed out. (connect timeout=10)'))
2018-07-23 10:51:24 ERROR (SyncWorker_5) [homeassistant.components.media_player.braviatv] 'NoneType' object has no attribute 'get'

Is there any way to rise the time out or the max retries? Or any way to see if this is a HA or my Sony’s fault?

Thanks
