mimoLive Reporter 2.1 dont work LTE and 3G

mimo LiveReporter 2.1 does not work LTE and 3G, no connection with the program. Only works on one network wifi. How to fix?

Do support representatives ever answer any questions here? Or bought the program and suffer? The question is directly related to the functionality of the program. Why is there no connection when using the mobile Internet? previously everything worked on the first versions.
