Copy the URL that gives you trouble and paste it into the address bar. You said that pasting the URL directly works. Does it for that URL?
From there on you can try to reach that server by using the ping command in terminal. You can see if the DNS is properly resolved to an IP and also if any connections are blocked to that IP.
traceroute <host> might also give you a hint on what is going wrong.
Deleting my history fixed it for me.
Safari > Bookmarks icon > History tab > Clear
Something in my history was poisoning the search results, and causing Safari to choke whenever you trying to type something into the search field. Since Safari tries to suggest pages that you’ve visited before, if a bad site shows up there, it can (presumably) cause things to go wrong.
In my case, the problem site was particularly bizarre. I dumped a copy of my Safari History using iExplorer before I wiped it, and started looking for unusual entries. These two stood out to me:
Title URL Visits Last Visited
Cannot Open Page <long Facebook url> -7 14 Aug 2015, 17:16
Cannot Open Page <long Facebook url> 1 14 Aug 2015, 17:12
The Facebook URL is an authentication page that was apparently launched by an iOS game. I don’t understand how it can be last visited in the future (that date is nearly two months after the problem started) or have negative visits.
I’m genuinely mystified as to how that item entered my history – I barely play the game in question, and I’ve never messed about with the date/time settings on my phone. And I have no idea how you get negative visits – possibly some sort of overflow somewhere?
I think it’s likely that this item was the culprit, but how and why are total mysteries.
