There are some environments where you may find when the Freeway Setting "Network" is set to "Remote", it works fine outside of the organisations Wifi network, however when that device is connected to that organisations Wifi network, the API connection fails and displays an error.
This error is caused by that organisations router, not being able to convert the External IP address back into the Local IP Address. Most recent models of routers allow for this, however some do not. Therefore this is a router problem rather than a Freeway problem.
You can prove this is the case by entering in the External IP Address and Port ("External IP Address":"Port Number") into a web browser that is connected to that organisations network. If the page fails to load, this indicates the problem described above.
To resolve this problem, it is suggested you contact that organisations IT Support Provider and convey the following:
"The router is unable to convert the External IP address back into the Local IP Address"
