Hii,Yesterday I had installed a new ubuntu machine and tested the communication between the android client and the clinical server. It worked without problems, I could create a questionnaire and reply on it on the android client. Today morning I had tried the same, and I could still see the answers on the clinical server.But here in the evening I tried again, and now the problem occur. I couldn't reply on a questionnaire and see it on the clinican server, furthermore I couldn't see the new questionnaire I had created and assigned to the patient. This problem had occurred two times last week, and therefore I had created a new machine, because I though it was some mistake on my machine, but I don't think that. Can you help me, and see what the problem is?The first day I create the machine everything works, but afterwards the next day, it doesn't work./ Rebecca
