Hi
I have been using Kaspersky and Slack together for many years. Very recently, Slack has broken for me and is unable to connect. I went through all the troubleshooting with Slack, including a total reset and was still unable to connect. However, when I disabled Kaspersky, it started to work again.
I narrowed this down further by going to 'Settings -> Network Settings -> Monitor selected ports only -> deselect 443'. Confirming and reopening Slack will cause the application to work again.
Naturally, I don't want to disable 443.
To reitterate: This appears to be a recent change as I have used both for years together without an issue.
Any ideas on how to fix this?
System:
Windows 10 21H1
Kaspersky Total Security - 21.3.10.39(i)
Screenshots:
With 443 enabled:
With 443 disabled, Slack connection is okay:
Thanks
