Can't reproduce, that code works for me. If you can reproduce can you try without adapter?

Issue seems to be the browser blocking fingerprinting. What's weird in this case is, that the unblocking-menu of Brave does not show this, sometimes isn't even accessible. So definitely a browser issue, but maybe calls for better error-handling. Will investigate further.

feross/simple-peer#701 has a pretty good description of the issue.
