Looks like for some reason it failed to successfully do ICE negotiation
potentially on the newly added remote streams. Why that is is
environment specific - but the problem does seem to be on the web
browser/client side, not in Asterisk itself. You'd need to figure out
why.

This is one of the annoyances of WebRTC - the browser can be a black box
at time and when things go wrong (like this) it's hard to dig and figure
out what is up.
