Netatmo Thermostat problems

It seems that the binding is not correctly working in OH 2.2 #1051. It works correctly for some hours but after some time it stops to connect to netatmo website for updates. I enabled logging and I cannot find any error. When it works every ten minutes writes:

2017-10-12 23:57:22.457 [DEBUG] [netatmo.handler.NetatmoDeviceHandler] - Trying to update channels on device 70:ee:50:1e:88:1a

2017-10-12 23:57:23.222 [DEBUG] [.handler.AbstractNetatmoThingHandler] - Updating device channels

and it shows the HTTP connection in Karaf console.
But after some hours it stops without any error. is there something that I can check?
