Problems with Safari - server not found - for no reason!

All. I had the same problem. Please see:

IOS 11.0.3 WIFI & MOBILE DATA NOT WORKING

My problem has a temp workaround. If I disable LTE (4G) the iPhone 6 I have goes into 3G mode and my problems disappear. Read the other thread, there are fixes that worked for some, but not for me.

I know it's years late but I googled this question today. But I don't understand the answers. How would I know if the DNA (or whatever initials you said ) are correct? Or if my watchigoohie or whatever the pre

Read your second paragraph. Would your grandmother understand it?

Poor Grant wondering why this crazy old lady is writing again. I don't mean to intrude into your undoubtedly helpful (for your peers) article. It's just that I don't know what to do anymore, so I'm using your reply to questions I need help with as a place to set

forth issues that affect me and others like me, in the hope that some of the people who read my problems may share them. And that we could at least make the various tech companies and ISPs and even better the FCC aware of the unresponsiveness of the companies to our needs. Especially the monopolistic ones who have no motivation to be helpful to anyone, let alone those who need more help than you yourself do.

This is the response that solved my "days old" problem of "Safari cannot open the page because the server cannot be found" as well as not letting me get into my ID under Settings>Apple ID>(my name)>Password & Security.

Sometimes the simple answer is the best one. Thanks LomasNZ! Now I don't have to pull my hair out any more!

safari or any Internet Browser does not open pages by name -- only by IP address. When you specify a name, a request is sent to a Domain Name Server (DNS) to get the number.

If you have not specified the DNS numbers, or you are using unusual ones, or they have been changed for some reason, sites may not be found.

¿ Are you using the DNS numbers specified by your Internet Provider?

Hi

I have been having the sane problem with two different iPhones on the same wifi network. But not with my PC on the same network.

Indeed I could not even get to this forum page due to this error. Until I tried using the 'private' feature of safari. That resolved it enough to enable me to get to this forums and the I found the following post and the first instruction, to reset my network settings on my iPhone, has work successfully for me. Although I have not tested it for long.

Settings>General>Reset>Reset Network Settings

Good luck.

Further to my post above the solution I posted did NOT work.

The problem is intermitant and so I get short periods of times when thing do work. The problem is persistant across iPhone 5, 4, iPad 1. On wi-fi. And on Safari and on Chrome.

I do not get this problem on 3G from the above i devices.

And I do not get it on my PC.

Frustratingly I often can not get to these forums.

I am beginning to wonder if this is a DNS TTL issue. This rather technical article (http://www.saurik.com/id/3) points to an issue with DNS CNAMEs in the iOS OS.

I noted on a seperate forum post that "discussions.apple.com" is directed to via a CNAME. Thus that might explain why I sometimes have a problem getting to this forum. Noting that there are many sites that I never have a problem getting to (eg, Google). Perhaps becuase these are DNS A (Address type) records?

What appears to make things work , for a while, are minor changes that I might presume cause any DNS cache to be cleared. Eg, clearing cookies and data; turning off and on the wi-fi.

Although that does not explain why things work (as far as I observe) via 3G. Does 3G have an alternative DNS cache algolrithim?

Very frustrating.

Those are really interesting theories, but you are massively over-thinking this. You do not have access to CNAME records, and TTL problems would be affecting huge numbers of Users, not just you.

The usual problem is that the DNS numbers in use are damaged or absent, and your query gets hijacked by an internet site pretending to be a DNS.

¿Exactly what DNS numbers are being used by the devices having these probelms?

I can provide my DNS number. That will be my wirless modem. And for the record I have checked it and it is present and correct. What my ISP uses in terms of DNS... I have no idea. And they may indeed be at fault. So I have also logged a call with them.

Based on further observations that my PC/Windows7 does exhibits the same error, but appears to resolve itself faster; flushing its chache; Ctrl+F5 on that browser helps with that. Then I think the issue is off the device (Windows and iOS have the same problem at my house). However, I think what iOS is doing is caching for longer [than Windows] the invalid response which it is getting from DNS. Meaning the issues lives for longer on iOS.

I also have had the problem now for a few weeks.

Safari randomly comes up with 'Safari Can't find the server' errors loading webpages, when everything else works fine. My internet connection is fine, and if I copy and paste the exact same link into Chrome, it loads no problem.

Try a refresh in Safari, but it still says cannot find the server, so clearly the server itself is fine, and the internet connection is fine, it is just Safari that is not working.

Any ideas what would cause this?

I'm currently on 10.9.2 and Safari 7.0.3

What would cause this is just what I mentioned above.

You MUST be using a valid Domain Name Server to look up your symbolic addresses into IP addresses so that sites can be contacted. It is easy to get a bad DNS Server, and the information sometimes comes from bad info entered into your Router. Bad DNS references can also be caused by certain malware.

You must use one of:

• The EXACT numbers provided by your ISP.

• The numbers provided by a Public DNS server such as (in the USA) Google DNS or Open DNS

Apple advisor had me do the following and it seemed to work

prefernces

users/user groups

login items

all the items/apps are trying to open at the same time and some may show a yellow conflict sign. he had me delete all of them and restart. seems to have worked.

Think of the information highway in terms of how real highways are affected by storms, fires, mudslides, accidents.

If an artery that normally handles fast traffic is shut down, the traffic is rerouted to roads that now become clogged with traffic.

If you have an important meeting and would be on time if you were on the highway - you will be late - or time out to make the connection.

Then there is too much traffic so it is almost denial of service.

Just about 15minutes ago - had a server error message from this site - 3 minutes later same page through this site and it was fine.
