Am also getting this issue. Strangely only affecting the minority, haven't found a quick fix as of yet.

1. Update from your existing Avast version via Settings -> Update -> Update program won't work -> DNS resolve has failed...
2. Or you can download and install from here -> in this case, what happens with the actual settings?

Hi,

This issue has been fixed in version 18.6. This version will be widely distributed to all client devices on the 17th September.

If you require 18.6 on the devices now to resolve the issue, you can uninstall 18.5 version, download 18.6 from the console and deploy to those devices.

Regards,

Sean

WTF, who has time to uninstall and reinstall for 50 machines or so???? You? if so, then you got too much damn free time on your hands...
the fact the matter is that this should have been fixed weeks ago, not until next week or so.

A new version of Avast Business Managed Antivirus is scheduled for release on September 17th, 12:00 UTC.
Since September 10th the version 18.6 has been available for new installations only. Starting this rollout your AV will be updated automatically in following few days (according to your settings).

*Note: a restart of the workstation may be required.

Is there any update on the rollout? I've just reinstalled. Console is on 6.x but clients (even after a new download, both offline and online) are still on 18.5.2535

Didn't even realize I was having this issue until I wondered why my mail server was dragging a bit (was a bit out of date).  I did have to uninstall the aVast business antivirus / agent components out of add/remove programs for 18.5 and reinstall on my management server using the on-premise console (6.0.8).  I also use that machine as my master agent / local update host which had to be redone, but once there the other machines seemed to filter through.  Didn't have to reinstall the management console at least.

Same problem here.
We just moved to Avast Antivirus Business Managed and I was implementing the Avast Master Agent and then when i force update in a client it looks like it can't find the local update server(DNS resolving error) and ends up by doing updates from the Avast servers, so it's not working!

I've updated ~25 clients to the version 18.6...

Still same error (DNS resolving error) via local mirror C:\ProgramData\AVAST Software\Persistent Data\Avast\Logs:
https://pastebin.com/raw/SZZ8yVf1

Now had no idea how to fix it...

And how I've empty entry '' for IP\DNS in mirror's setting file even after full client reinstall?
C:\Program Files\AVAST Software\Avast\setup\smbupd.def:

Code: [Select]
[servers]
maintenance=0
count=1
override=0
[mirror]
enable=0
allow_fallback=1
[server0]
name=Download Mirror ABS Server 0

Hi Assist2,
I'm sorry you are still having an issue with the mirror server, we thought that the bug is already fixed with the release of AV 18.6.

Firstly, please, could you check that the station is really available via. "ping" and "tracert" to the mirror server?

Secondly, please, could you enable the debug logging, restart the "Avast Business Console Client" service and send us the log files after the content of smbupd.def is newly overwritten?

Thank you in advance
