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.

Looking at Reddit, several people are noting this there too - appears to be related to the networking stack and possibly incompatibility with Firewalls/Filters (Little Snitch, Radio Silence, etc.).

Thanks, unfortunately I'm not using any antivirus or anti malware applications though. I'm glad I'm not the only one experiencing this issue. I did submit feedback and hopefully Apple releases a fix soon.

Hopefully they release a fix quicker than the two-week cadence of updates.

Based on the feedback I submitted for Firefox connection timed out issue, a fixed has been identified for a future release and there are more then 10 similar reports. This is good news.

I had this issues too. Just disabled network filters for Cisco AnyConnect and Endpoint Security and now its working perfectly fine.

Not sure what you have set up, but whatever port I set opens fine. Using 4.0.6 here. I haven’t updated to the newest version, I found it visually unappealing on Tahoe, maybe it will look better on GG.

It looks like Apple released a revised version of beta 3. According to one reddit comment the network issues are fixed. I'm downloading the updated revision now and will report back.

Edit: It looks like the revised version fixed the network issues for me.

I successfully reinstalled CrowdStrike Falcon without any issues.
