Symptom Network connectivity stops completely I've now experienced this twice.. After using STP 96 for a while (a day or two since reboot this time), I experience a page not loading. nothing unusual there, until one goes to a different browser - for example google chrome, and find that the site/page is fine, and responsive. In my case I initially saw a failure to load a page from BBC iPlayer ie https://www.bbc.co.uk/iplayer . I then went to my 'gmail' tab to see it report 'not connected. connecting in 1s' . I type into the search bar, and get nothing (no dropdown showing search results, no google search). Going specifically to 'www.apple.com' and I just see the progress bar at perhaps 15% and not moving. I also tried my local router web page - same, and even http://127.0.0.1 I had been running a video (BBC newsnight) in PIP mode. It did stop a few times (oddly) and I had to go back to the main frame and do pip again - that was the only oddity. Using internal display & external 4K. MBP Pro 2016 Interestingly I don't seem to get an error, just an apparent hang CPU usage is normal (extremely low) I have in the order of 20 tabs open. Environment - Catalina beta 10.15.2 Beta (19C46a) - wifi (up to around 600 Mbps) - backend router 1 Gbps down / 50 Mbps (up) - no additional firewall/AV on mac I experienced page loading with issues prior to 96 as per https://bugs.webkit.org/show_bug.cgi?id=201822 Unsure what else I can capture. I clicked on 'report an issue' but of course bugreport.apple.com does not load If I open web inspector I see no activity - I get the usual tabs but the console has nothing in it, nor does timelines or network - even if I try and reload the page. I don't even get a page loading timeout, it just sits there It's as if the entire back end/network layer has given up. In /Logs/DiagnosticLogs I see nothign relating to safari - indeed nothing for the last few hours (as expected) Twitter, spotify, intellij, chrome, whatsapp, slack etc are all working just fine, so this doesn't seem a systemwide problem, ONLY safari tech preview. I also tried 'empty caches' - no change
I opened a new page in private mode - it hung too.
A search in console for 'safari' shows this pattern repeating - it may be the cache entries were after I hit clear cache (though it's 10 mins later now) but the network error unknown error code 1100 May be interesting? default 10:39:15.501580+0000 deleted com.apple.SafariTechnologyPreview.CacheDeleteExtension : 0 default 10:39:15.501924+0000 deleted com.apple.Safari.CacheDeleteExtension : 0 default 10:39:15.502542+0000 deleted PurgeableSpace result: { "CACHE_DELETE_ELAPSED_TIME" = "0.031671062";

If I can/remember I will leave up in broken state in case the team have any further debug info to request that would be useful, but it's unlikely I'll manage this beyond the day...
I left STP up all day (whilst using regular safari mostly) and can confirm it's still in the same state - no no error/timeout pages came up, the pages I left 'loading' still have a ~15% progress bar.

Thank you for the report! The most useful thing to do right after getting an error like this is to collect a sysdiagnose. You can press Cmd+Opt+Ctrl+Shift+Period or run "sudo sysdiagnose" in Terminal. Once you have it, please file a report with Apple via <https://feedbackassistant.apple.com>, attaching it there. Once you have the number for that report, please post it here to make it easier for us to find.
Thanks - I will do that if it reoccurs. Unfortunately just before that last post (sat eve in uk) I decided to restart STP (which worked fine) and shortly afterwards applied 19C56a. I'm using STP now but can't capture further info until/if it reoccurs. I'll bear those instructions in mind if it does so thanks.
we at www.krone.at expierence the exact same error with same fragments inside the konsole log - on iOS and MacOS Safari 14+ (even in beta2 of 14.0.1) i filed a feedback with a full sysdiag FB8806325

It's been a couple of years since an update -- is this still an issue?
