Beta 3 internet connectivity issues in certain applications

[Mac_tech]

After updating to beta 3 of macOS 27, websites fail to load in Firefox or Opera. Dropbox fails to connect and telegram says connecting. Also when I open music, it's stuck on loading iTunes purchases.

Safari seems to load websites fine.

On beta 2 everything worked fine. I don't use a VPN, just connect to the internet via WiFi.

Any help would be appreciated.

Transmission gives me problems too, I can't make to port open for whatever reason ;/

I have these same issues, plus it impacted my wireless printer and Mail.app. Beta 3 seems to have gone off the rails.

Had the exact same issue. Turning of limit IP tracking in Wi-Fi/ethernet settings helped temporarily. Ultimately, uninstalling CrowdStrike Falcon fixed it.

I would first disable/uninstall any antivirus/antimalware apps and see if that is causing it. It's a huge pain to uninstall/disable them, but you may find the solution by doing so.
