I am getting regular emails about my readynas' AV being out of date. I logged on and ran freshclam getting back

Seeing a few other examples I tried
host -t txt current.cvd.clamav.net
current.cvd.clamav.net descriptive text "0.103.2:59:26168:1620826140:1:63:49192:333"
and it wasn't until I ran wget that I got somewhere

I tried from other sources. I don't know if this is something going on in my network or other people are having this problem. It is resolving and I am not seeing a firewall error. Best I can tell it is something on ClamAV's side and I don't think it is an unsupported version.
We are still investigating why the AV database is still not updating for some users even after updating to 6.10.5.
For this particular case, L3 checked /var/lib/clamav and saw that daily.cld was still outdated. L3 needs to renew it so they removed the two files (daily.cld and mirrors.dat) then ran freshclam.
If the user is knowledgeable in Linux, they can try this, but it will be best if they can send the logs to me or @Marc_V so we can forward this to the appropriate team and they can further investigate the issue
May I know the model number of your ReadyNAS unit and the current firmware of it?
If the firmware is not yet on 6.10.5, you can try updating the firmware to it. The 6.10.5 firmware addressed an issue wherein the ClamAV fails to update the database. You can read the release notes here.
I upgraded to 6.10.5. and that did not fix it, still getting an error
Now, worringly, it will not let me connect to the admin web page. It gives me the password prompt then goes through the "Connecting to ReadyNAS Admin Page" and kicks out with a timeout error.
Fortuantly, I can still ssh into it and access the file server, though RAIDar 6.5.0 does not pick it up.
If you are still not able to access the admin page or if the NAS is still not detected on RAIDar even after rebooting it, you can also try doing an OS reinstall and see if that helps.
Can you download the system logs of the NAS then provide them to us so we can further check? You may upload it to a cloud storage site then send me the download link via private message.
Though there could be another root cause, other users are reporting AV update issues. Is this something you can share and users can check for/fix themselves?
