问题
My .net BOT hosted in web chat is neither responding nor showing any error at application insight.This error had been earlier some months ago but at that time it gave "Gateway timeout" error and next day it started working automatically.But this time it showed same "Gateway timeout" error but doesn't get started even after 1 day and now it is neither responding nor showing error.Meantime my azure subscription plan changed from S1 to F1 but now I changed it to S1 again.
