Answer 1

What the error message says. The first server in your list specifies no username or credentials:

{url:'turn:numb.viagenie.ca'},

You also repeat the same server further down, this time with credentials.

These also look like non-working turn servers cut'n'pasted off the internet. Free turn servers is a lie.

Also waaaaay too many servers. One or two stun and/or turn will do. Too many slows down ICE.
