The VPN traffic is too high, how can I reduce the number of GB used?
Use the Connection Log Report to identify the origin of the excess traffic.
This report gives all the traffic/data usage details per Ewon device and all the connections.
This document is useful to identify at a glance which devices are most often connected or staying connected and probably creating unnecessarily/accidentally large VPN traffic.
You can find the Connection Log Report in the Account section, then under the Report button.

it is important to close the connection to your device when troubleshooting investigation is completed (Ecatcher/Disconnect).
Long M2web/Ecatcher mobile connections can also be checked on the Connections section of the report.
