Hmmm... Isn't it rather self-explanatory? Your nameserver was trying to
send a response back to a client, but there was a network error.
"Connection reset" implies that the response was made via TCP (UDP is
connectionless), although sometimes error-code-to-text routines get a
little over-specific, and maybe this was UDP after all.

In any case, if your clients and servers are separated by a firewall and/or
router filter, you might want to review the TCP rules in the relevant
device(s).
