hello raychu,
after much head-scratching, we have a suspicion as to what could be going on here. in your problem description, of particular note is the part where you say that the units are installed in remote locations. and you didn’t say so, but i assume that the computer where you are running the FE config app is local? meaning that communications between your browser and the Shakes happens across a network where there are possibly routers and firewalls involved?
when this is the case, there are two ports through which traffic must be able to flow:
- 8765
- 8766
one is used for the keepalive signal, while the other is used to transport the live data displayed on the home screen.
please confirm the following:
- any and all firewalls that may exist, between the computer where you run the FE app and the Shakes you need to access, have been configured to allow all traffic to pass through the two ports listed above, in both directions.
once this has been done, please report back the effect, if any, on how the FE app behaves.
thanks in advance,
richard
