Steps to reproduce the problem:
I was manually going through and setting up an RTC connection during development and I got an error on iceconnectionstatechange which just said "fail". My screen looked like this (not mine but pretty identical)  https://i.stack.imgur.com/GaXoP.png

What is the expected behavior?
This led be to believe that there was a connection problem elsewhere when in fact there is a 15 second timeout on those connections, which my manual signaling process exceeded. There was no documentation I could find that said anything about a 15 second timeout, nor was the error helpful. If the error had said "failed: timeout exceeded" or something like that, it would have been very useful 

What went wrong?
There was a pass fail error message displayed
