Hello,
today I tried update using VRM EVCS firmware as usuall to version 1.28 (from 1.27). VRM update always failed with error msg "The site's two-way communication service stopped responding. Please verify the internet connection and/or try again. Error: 1302:"
I was able to manually update firmware 1.28 using web interface of EVCS, but after upgrade and resetting unit, EVCS lost connection to my WiFi network (UniFi WiFi network using WPA2). EVCS could see all WiFi networks broadcasted by UniFi AP, but couldn't connect to any of them.
Downgrade to 1.27 resolved the connection issue. I have noticed in changelog improvement "Improvements in WiFi module configuration and handling logic". Have you really heavily tested this improvement?
