Unable to resolve: connection refused (Linux Mint)

[elXames]

Hi there!

I tried setting up dnscrypt-proxy on a freshly installed Linux Mint system. I did everything as described in the 'Installation on Linux' section in the Wiki. But after stopping and disabling the systemd-resolved service and configuring the relsolv.conf file, ./dnscrypt-proxy -resolve ... only spit out this: Unable to resolve: [read udp 127.0.0.1:44342->127.0.0.1:53: read: connection refused].
Also, the resolv.conf file was reset with the following code: # Generated by NetworkManager nameserver 127.0.0.53.

I have no clue how to fix this...

Hi @elXames,

I don't run Mint, but I'll try and help ( in lieu of someone stepping in who knows better).

I might be tempted to set 127.0.0.53 in the dnscrypt-proxy.toml file
(I prefer to keep it simple)

The way to stop nm overwrting resolv.conf is to edit
/etc/NetworkManager/NetworkManager.conf
and add a line dns=none to the [main] section

QQ:
when you were following the instructions and got to the part where you run

./dnscrypt-proxy

Were there any error messages? Was that part clean?
If you leave that running in one terminal window, and open another, what do you see if you run
ss -lp 'sport = :domain'

I have a mini ubuntu server - that has resolv.conf set to 127.0.0.53 rather than the expected 127.0.0.1
Trying these can help debug a little, depending on the result from the ss command output and what you have in dnscrypt-proxy.toml
