Thank you for your answers. Do you think problem could be on ISP side? Upstream resolvers are:

213.46.172.39 and 213.46.172.38 (Luci says)

dig @213.46.172.39 www.cssz.cz works OK.
dig www.cssz.cz returns nothing

/etc/resolv.conf:
nameserver 127.0.0.1

I am out of ideas where to look next :slight_smile:

EDIT: I put IP and name to /etc/hosts as a temporary solution.

I see no indication what could cause the issue (and it doesn’t happen for me). Can someone catch the failure with verbose logging? https://wiki.turris.cz/doc/en/howto/dnsdebug#install_resolver-debug_package

MOX Classic, 5.1.2
Tried to install according to above document, unfortunatelly, error:
"Manually install package
The package resolver-debug is not available in any configured repository.’

Package resolver-debug is compiled and I see that it is present in HBT and HBK, where is a version Turris OS 5.1.2.

E.g. https://repo.turris.cz/hbt/mox/packages/turrispackages/resolver-debug_0.0.1-10_aarch64_cortex-a53.ipk

Did you run opkg update before trying to install it?

Sorry, I didn’t update package lists as in step 2 of doc. I didn’t understand instructions well, mea culpa. Now is it installed. I’ll try to continue debug resolver.

Tried to debug resolver, at no avail. Win10 Google & Firefox resolved www.cssz.cz OK, as well as android Google… Sorry.

I’d say that the original error was a casual (random) one, according my own expirience.
