Dns-crypt not working after hard reset and restoration of settings

Installing and Using OpenWrt
1

I just resetted my router (using firstboot command in failsafe mode), and then I reinstalled all additional packages I had before, and using LuCI to restore from a fresh backup. Now DNS-crypt doesn't work. It worked perfectly before, and I used this guide to set it up.

Now; when I run logread -e dnscrypt-proxy; netstat -l -n -p | grep -e dnscrypt-proxy

it shows

Tue Jan 19 19:31:40 2021 daemon.err dnscrypt-proxy[2241]: [2021-01-19 18:31:40] [NOTICE] dnscrypt-proxy 2.0.44

Tue Jan 19 19:31:41 2021 daemon.err dnscrypt-proxy[2241]: [2021-01-19 18:31:41] [FATAL] No servers configured

However, the config file is restored and contains the line: server_names = ['doh-northeu-pi-dns', 'doh-centraleu-pi-dns'].

I can't resolve any hosts from the router.

Also /etc/init.d/dnsmasq restart gives

udhcpc: started, v1.30.1 udhcpc: sending discover udhcpc: no lease, failing

What could be the issue?

It looks like dnscrypt-proxy2 relies on the server list downloaded from the Internet:

The servers you have configured do not present in the current server list:

So, update the config to use up-to-date server names.

Thank you @vgaetera! That's it! Somehow the old config worked fine even though it used the outdated server names before the reset.

The service downloads the server list and uses its local copy.
However the directory /etc/dnscrypt-proxy2/ is not preserved by default.
You can customize backup settings and include it in the backup list.

Oh, didn't know that. Thanks, I'll check it out!
