Pi login probleem/reboot problem

[jannl]

It seems not possible to login to my pi at the moment with the default password. (As far as I know I did not change it.)

When I issue a reboot from the webinterface (or a shutdown) I get the following messages.

2016-06-26 22:25:24.929 Error: Error executing reboot command. returned: 35584
2016-06-26 22:31:00.787 Error: Error executing shutdown command. returned: 35584

Any clues?

Edit: http://192.168.1.2:8080/json.htm?type=c ... tem_reboot gives 'Err' back.

I have the same problem.
All of a sudden I can not SSH into the Pi anymore, it gives Connection refused.

Domoticz seems to be running fine, sensors get updated and according the log messages scripts get executed as well.
However if I try to reboot the pi through the Domoticz webinterface it gives the error: Error executing reboot command. returned: 35584

Anyone have any ideas what may cause the problem?
