@notflexiblee Hello! Sorry, your post had been stuck in pre-moderation.
Seems it's a bug.
To analyze it we will need:
our traces (by default it's in C:\ProgramData\Kaspersky Lab\AVP21.20\Traces . please check that they are set on max level)
wire shark logs
additional info. Can it be reproduced easily, or it takes time to face it? Have you checked it in other browsers?
