After I upgrade to macOS 15.4 or later, BrowserStack sessions stop working in Chrome and Edge, but continue to work in Firefox. Why does this happen and how do I fix it?

BrowserStack sessions stop working in Chrome and Edge after updating to macOS 15.4 or later due to a known issue with how Netskope handles QUIC traffic, which disrupts all WebSocket connections.

As a workaround, configure a Netskope Private App for BrowserStack with the following settings:

   - Host: *.browserstack.com

   - Protocols and Ports:

       - TCP: 443

       - UDP: 443
