TLS handshake slow, times out after Mac Mojave update

Posted

This has now happened after the last two Mac updates. I get the TLS handshake forever until it times out. Occasionally something gets through (like the Mozilla help pages!) Unlike others who have posted this issue, the same problem holds in Chrome and Safari. I have tried various fixes, including a new identity on my Mac, with no success. Last time the issue seemed to spontaneously resolve after a couple of hours and never reappeared until Mac updated again. While all this is happening, my email works fine, my husband's macbook pro (just like mine) works fine, and my iPad works fine. I have left this message on the Mac help forum, too, hoping someone will have some idea of what is happening. OS Mojave 10.14.6

Make sure you are not blocking content.

Start Firefox in Safe Mode {web link}

A small dialog should appear. Click Start In Safe Mode (not Refresh). Is the problem still there?

Same problem in safe mode. Google sites are the worst affected -- won't open at all. Firefox support opens easily. Some other sites open before the system times out.

Remove History For One Site

Open the History Manager <Control><Shift> H. In the search bar, enter the name of the site. Right-click on one of the listings and select Forget About This Site. This should remove all information, including any settings.

Did you try to disable IPv6 ?

Are you possibly rolled into TRR (Trusted Recursive Resolver) or DoH (DNS over HTTPS) ?
