I've noticed this happens fairly regularly with v0.7.0 [dnscrypt proxy 2.0.31]:

PS C:\Windows\system32> nslookup www.bbc.co.uk DNS request timed out. timeout was 2 seconds. Server: UnKnown Address: ::1

DNS request timed out. timeout was 2 seconds. DNS request timed out. timeout was 2 seconds. *** Request to UnKnown timed-out

Query log shows requests timing out:

Toggling the DNSCrypt Service allows requests to work again.
