Title: DNSCrypt-Proxy kernel: Connection attempt to UDP 127.0.0.1:x from 127.0.0.1:5353
Post by: 0p3n3y3 on March 30, 2020, 11:18:31 PM
Hello. I get this problem and sometimes DNS is not working anymore. Does anyone please know a solution for this problem?

I AM running "Unbound DNS" on UDP port 53 and "DNSCrypt-Proxy" on UDP port 5353 and the system logs get non-stop bombarded and overflowed with the same messages below.                                                                               

Code Select

I have put the custom settings in Unbound DNS for DNSCrypt-Proxy to work recommended by the official documentation at: https://docs.opnsense.org/manual/how-tos/dnscrypt-proxy.html

Code Select
do-not-query-localhost: no
forward-zone:
name: "."
forward-addr: 127.0.0.1@5353
