Initially thought this was a DNS issue but I've been having real problem resolving a lot of .com domains.

So I checked over 4G network and had no problems. Thought it was ISP but others on same connection not finding any issues. So what changed?

10.13.4 > 10.13.5 is what!

So I am now immediately suspsicious it's related to this but I don't know how or why. Maybe a bug.

Pages are timing out in safari. Taking 10/15 seconds to load if they do. Suddenly everything works again. Then it's gone again.

Any tips appreciated. Thanks.
[doublepost=1529415328][/doublepost]Yep seems it's Safari (macOS) - Chrome is working fine when Safari "can't find server" :(

I cleared Safari's caches but made no difference. Safari is behaving as if it's got intermittent connectivity.

I am having the exact same problem and have done the same as you. Clearing the caches seems to help briefly.
 
This is really a major pain - first, to get network utility app in High Sierra (I thought this was always in utlities), you'll find it here:

/System/Library/CoreServices/Applications

Trying both www.google.com and www.apple.com I got the following error

Lookup has started…
www.apple.com -> The operation couldn’t be completed. (kCFErrorDomainCFNetwork error 2.)​

Also tried to ping both URL's, that also failed but then it worked a few times too.

I also changed DNS to the following:

OpenDNS
Preferred: 208.67.222.222
Alternate: 208.67.220.220​

Moving on:

I check the airport utility, and see this message...

No configured airport base stations have been found. ​

This could be part of the problem. We shall see...

So we're back to same internment connectivity.

I've been on Beta 10.13.6 (that solved the original problem) and now 10.13.6 - yet for some reason today it started again - so tried the safari preview build 12.0.0 - this seemed to make not immediate difference.

It's not as 100% as bad, so for example I can get to google.com but not twitter.com - all these sites check out in alternative browser like Chrome.

Some things have improved the last hour but Safari, what is up with Safari these days?

Same. iOS devices work fine.
Super annoying, I'm doing research requiring multiple sites.

Try tracert instead of pings, then it will show you how far it gets to the url host rather than just "it failed" (or worked).

Traceroute? Is that what you mean?


Basically I have to hit page reload multiple times on some pages, their connectivity but it's consistently inconsistent on any site. Some less that others.

I'm on S12 seed 4 but it's been happening before this and was the prime reason to move to dev version before 10.13.6 came out.

It's affecting everything that needs to reach out on the net. From terminal to safari resolving url's in a timely manner and on first hit.

Still Chrome works fine but the core connectivity of the OS is having some serious problems beyond my understanding.

Is there any darn solution to this problem??????

Yep - tracert is the command line

I can't get that cmd to work (but I could via network utility app) but it probably doesn't matter since Chrome can resolve URLS no problems.

I was installing some software using cmd a few days ago and keeping erroring out as it couldn't reach out and resolve to grab files on GitHub.

This is a OS issue surely at this point, something is wonky at the heart of the OS / Safari connectivity heart.

It's driving me nuts - I have to refresh pages to load at leat once or twice, every time... CMD + R keys arming to wear out! Can you imagine trying to deal with any based web form links/posting.

When anything doesnt work, run the tracert from the network utility, otherwise you are still just guessing and hoping for someone to just tell you what is wrong...
 
I am hesitant to say but the latest update seems to have stabilised the problem.

Safari - Version 12.0 (13606.1.36.10.3)

I have not encountered a "Cannot find server page" once or had to hit CMD + R

To think I lost nearly a whole days work fighting with Safari hours before the update arrived but that's not all it's been going on for as long as this thread has existed. I know i am not alone but man you take productivity hit when Apple drop the ball for weeks on end.
 
Yep it's started again now on Safari Version 12.0 (13606.1.36.10.5), though fine since Aug 16th post. There also seems to be iCloud connectivity issues in the mix now. :(
 
Ok latest update for Safari 12 / macOS10.13.6 - seemed to help restore issues and signing into iCloud seemed to resolve itself also.

However there were still a few problems and I deiced to install Beta 11 of Mojave on this machine, once I backed up the upgrade went through without a hitch and normal service has resumed. Proceeded to upgrade the Beta and we seem to be on a GM build.

Current version of Safari Version 12.0 (14606.1.36.1.9)

In conclusion, it appears Mojave has resolved on my issues, including those pesky security issues around allowing other apps access. Things like Box sync have started working again among other apps + thank you for Stack, now if we could get the same or similar for Safari ;)
