Safari sporadically stops accepting page requests for a minute at a time

Hi,

Every-so-often my Internet equipment hiccups or the server I'm contacting is simply not responding. Maybe a packet got lost on the Internet highways. Whatever the cause is, the page request is not answered immediately. If I then wait 60(?) seconds, a timeout kicks in and displays a helpful message that the server is unresponsive. Impatient as I am, I have learned to recognise this after a few seconds, and the instinctive response is to hit refresh or click the link again etc, and the page loads immediately. I think anyone on the Internet know exactly what I'm talking about.

Except lately that hasn't worked with Safari. I think it started on OSX High Sierra, and I hoped it would be fixed by updating to macOS Mojave, but unfortunately the issue remains: I *have to* wait the full minute. I have no choice. Before the timeout refresh doesn't work. I actually can't open any page at all. I click other links on the page. I hit the refresh button. I try typing a search string in the address field. I try switching to another tab or opening a new one. Nothing works. Safari is apparently not sending any requests during the timeout. As if it has decided that the network is down, so there's no point in trying…?

And then suddenly the timeout triggers and the “server is not responding” text appears. When I refresh after that the page loads immediately. Everything works just fine. Until the next hiccup that makes Safari unusable for another minute.

Does anyone else have this problem?

Grateful for any help

Best regards

Johan
