I added a node using requisition, to test access to google DNS at 126.96.36.199, thus Ping and DNS services are detected.
Ping is OK, not DNS.
The same requisition on another DNS is working well.
I’m using Horizon v29.0.4 on a Debian 10, with ufw properly configured. (also not working with ufw disabled)
How can I debug this ?
Unless configured otherwise, the default behavior of DnsMonitor is to perform a lookup on an A record ‘localhost’ which is probably going to fail on most public DNS servers.
> server 188.8.131.52 Default server: 184.108.40.206 Address: 220.127.116.11#53 > localhost Server: 18.104.22.168 Address: 22.214.171.124#53 ** server can't find localhost: NXDOMAIN >
OK, so I’ll modifiy the “lookup” parameter
