Title: DNS request blocking -> no more internet
Post by: alain.dezetter on August 31, 2022, 08:18:34 AM

Hello,
For some time now (with free Avast 22.7.6025 (version 22.7.7403.744)), randomly, avast blocks my DNS requests.

If I deactivate all the agents, the DNS works again, then I reactivate and no more problems, until the next time...
Is this a known bug?

Kind regards
AD

Hi,

So disabling and re-enabling the Avast Shields cause the issue to go away?

Can you provide a support file ID (https://support.avast.com/article/Submit-support-file) and screenshots (https://support.avast.com/en-ww/article/Create-screenshot) of any DNS-related error messages?
