I’m stuck on stage 8 of dns resolver. I am trying to forward request to resolver and it doesn’t seem to work. I’ve tried to use UdpSocket::send_to(..) and UdpSocket::recv_from(..) and this doesn’t seem to work. I get response here, but it looks like the response I receive is not from the resolver. …

Finalllllyyyyy… I wish test could somehow find out these small details. Looks like the issue was I was sending qr flag as ‘reply’ (1) when forwarding the value to another dns resolver. After I made an update to send a qr value as (0) to indicate the packet is for query it worked.

This is very odd. I reviewed code from other members and looks like they are doing same stuff as mine. Anyone has hints on what I might be doing wrong?

Sorry we haven’t been able to help here! I’m not a Rust expert so unfortunately got to wait for someone to hopefully land on this and share some insight :slight_smile:
