Something prevents js from loading. Do you have firewall? Do you use adblock?
No mate to my knowledge I’ve no special blocking or firewall rules.
As workaround you can open it from girhub - https://github.com/blynkkk/blynkkk.github.io just open necessary md file.
Dmitriy, I will post logs when I get to my RPi. Meanwhile, here is my code…see anything here that might cause disconnects or strange behavior? Thanks!

Hi…a bit more information. If I start clean with a reboot of the server on the RPi the app works well. It appears that the disconnections start when the app is shut off and then re-started. This can happen either through disconnecting the iPhone, or stopping the app and restarting (although if I simply turn the app off and on using the “>” at the top it continues to work!) If I again restart the server (0.18.0) on the RPi everything works as it should. Not sure if this helps but it does appear to be a symptom of some kind of app to server connection issue. As I said in previous post, I am using WiFiManager with Adafruit Huzzah ESP board, and Blynk server on RPi 3. Thanks.
