@asmit27rai : Hi Asmit, great work on this fix 👏 This addresses a pretty critical regression in the DHT flow, and the root cause around the race condition in stream muxer initialization is well handled. Fixing the handshake failure with bootstrap peers is a big reliability win, especially since this impacts core connectivity. The changes are clean and focused, and it’s good to see CI passing and the newsfragment added as well. Overall, this looks like a solid and important fix that improves stability of the networking stack, nice job pushing this through.

CCing @sumanjeet0012 for his review and feedback. We should land it in the coming release.

@asmit27rai : There is just one CI/CD issue I noticed. Otherwise, ready for final review + merge.
