            Bug ID: 204940
           Summary: STP 96 stops loading pages after a while
           Product: WebKit
           Version: Safari Technology Preview
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2

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
