Electron Example Sketch

I was trying to use the example sketch for Blynk found here:
http://docs.blynk.cc/#hardware-set-ups-particle

I scanned the code and added my auth token but the project fails to connect to the Blynk cloud. I am running 0.4.8 version firmware on the Electrons. If I push the Mode button while serial monitor is open, I see a rapid scrolling of Connecting to blynk-cloud.com:8842. So I updated the firmware on my Electrons (I have 2) to 0.5.3.Now not only does it not connect, I am getting an occasional Invalid Auth Token. I have rescanned the code and reloaded the sketch 3 different times with three different Auth Tokens, still no luck. I am using an iPhone v9.1 and my Blynk app is up to date.

I have run out of ideas!
Thanks

Invalid Auth Token, means you have probably run into DNS issue.
Please try this exapmle, which we want to include with the next library update: https://github.com/vshymanskyy/blynk-library-spark/blob/master/firmware/examples/02_Particle_Electon/02_Particle_Electon.ino
