Getting a bunch of SSL failures regard POST/GET HTTP requests aimed at AWS in the HTML5 build.
There’s an easy solution to this isn’t there? Starts here:
The SSL certificate used to load resources from https://sqs.us-west-2.amazonaws.com will be distrusted in M70. Once distrusted, users will be prevented from loading these resources. See https://g.co/chrome/symantecpkicerts for more information.
The reason for this is that Google decided not to trust certificates that were created by companies belonging to Symantec and it seems that AWS still is using one of this now distrusted certificates. They probably should fix this in the future.
Have you checked if you can reproduce this warnings with another browser than Chrome?
Thank you for the response - here’s what I found!
Edge requires going back to WebGL1 and fails to load as far as my code at all -
actually repeats the load process right after serving utility.js. Can’t even get a functional console open during the load to diagnose.
Firefox loads the app and has the same app behavior as Chrome but for a different reasons - looks like my AWS signing code is failing to create the right keys. Will need more digging but meanwhile…
YOU WIN 
Thanks - will close the thread!
