Thanks for your reply. My devices are sending data to the server without a problem, but the data that is being sent does not change meaning that I don't get the latest records. For example, as I am writing this comment I am receiving data with two records and with timestamps dating 10 days ago. I have been searching the web for possible solutions hopelessly, it seems as if no one else has ever encountered this situation. I am willing to provide further information such as log files and configuration files in case you might want to look into the situation. Thank you again.
