Title: communications error to 192.168.3.1#53: timed out
Post by: olluz on February 27, 2026, 10:53:27 PM
Hi there,

what am I doing wrong if I get this error sporadically:

host 217.160.0.94
;; communications error to 192.168.3.1#53: timed out
94.0.160.217.in-addr.arpa domain name pointer 217-160-0-94.elastic-ssl.ui-r.com.

I've read somewhere that it might be related to IPv6 being enabled.

With host -4 217.160.0.94 I haven't encountered the timeout so far.

Any idea how to solve this without disabled IPv6? Or rather what did I do wrong to encounter the error in the first place?

Any help is appreciated.

Thanks in advance.

Since the error is sporadic, it's quite hard to know. But check the DNS resolver logs on OPNsense for a exact time you had the error.

I wouldn't think it has anything to do with IPv6 since the error is ";; communications error to 192.168.3.1#53: timed out" which shows that your machine was querying using IPv4.

Do you get a result back despite the error?

And what are you using as a DNS resolver on OPNsense? And the OPNsense has got the IP 192.168.3.1?
