Hi-
I was trying to demo COSY 131 with Wifi hotspotted to phone. With my laptop hotspotted, I was getting an error message while trying to log in to Ecatcher, though it may have been different from the attached photo. When I could get it, connections and response time was very slow. I uninstalled Ecatcher to see if there was a newer version and the issue went away. I think I was running 6.3.5 but I’m not 100%- I have 6.3.6 now. Customer had a similar issue on his laptop and got the error shown in the attachment. We uninstalled and installed latest Ecatcher from website and error went away.
Probably a worst case scenario using hotspot to WIFI COSY. Phone said signal quality was 3-4 bars- wish I had a LAN connection to see if that made things any better.
