When I tested the relay connection with the new version, I was able to successfully connect to the server peer, but a context deadline exceeded error occurred when calling NewStream because WithAllowLimitedConn was not used.

This error caused me trouble, and I finally found that it was a timeout in waitForDirectConn (because my environment could not successfully holepunch).

Logging the errors returned by waitForDirectConn can help more developers locate errors and know through code logic that WithAllowLimitedConn is needed.

LGTM. Can you make the line more verbose? I suggested an alternative.
