Strange "Accept incoming network connection" popup |
|||
Issue descriptionChrome Version: 72.0.3609.0 (Developer Build) (64-bit) OS: Mac When I opened the browser today I saw the dialog below. I clicked 'Deny' and everything seems to work. Was this dialog intended?

Hm, not sure how to track down where that's coming from. Maybe grab a CPU sample when that dialog is open and the thread that's trying to make the outbound connection will be blocked waiting for the result of the permission prompt? Also, what OS version is this on?

I'm on 10.14.1. Sorry, the screenshot is in German.

Can you grab a CPU sample from Chromium when that dialog is up?

I just had this happen locally. I'm trying to grab a sample but sample(1) is hanging :(
