[clamav-users] messages in freshclam.log

[Sohin Vyacheslav]

Hello,

Recently I found in freshclam.log messages like this:
Can't query daily.25671.105.1.0.6810DA54.ping.clamav.net

that was occured once per day about 11:30 p.m.

Another attempts to update clamav are successfull (before mentioned 
message and after) but next day this message is repeat.

I thought that the reason is connection error with IPv6 mirrors, because 
output:

$ freshclam --list-mirrors
Mirror #1
IP: 104.16.219.84
Successes: 53
Failures: 0
Last access: Fri Dec 20 11:29:39 2019

Mirror #2

Mirror #3

Mirror #4
IP: 2606:4700::6810:db54
Successes: 0

So I added these IPv6 clamav mirrors to /etc/clamav/freshclam.conf:

DatabaseMirror db.nl.ipv6.clamav.net
DatabaseMirror db.fr.ipv6.clamav.net
DatabaseMirror db.ch.ipv6.clamav.net
DatabaseMirror db.uk.ipv6.clamav.net

and restarted freshclam process. But next day mentioned message is still 
exists in freshclam.log:
Can't query daily.25671.105.1.0.6810DA54.ping.clamav.net

How it's possible to update clamav without mentioned error?

p.s. OS=> Debian 9.11
      ClamAV=> 0.101.4+dfsg-0+deb9u1
