Safari: kCFErrorDomainCFNetwork error 1 on local (HTML) files I keep a lot of local HTML files on my machine, including my home page.  Whenever I first open Safari, and often when going to any local file, I will receive an error.  Hitting refresh (or, for the home page, the home button again) fixes the problem... until the next time you try to go anywhere.
Usually opening a link in a new tab prevents this from occurring; opening a link in the same tab almost always sees the error.
I realize &quot;wait for Apple to get around to fixing it&quot; is a valid answer; I also realize &quot;use a different browser&quot; is a valid answer.  I'm hoping, instead, for a setting change I can make, or HTML tag I can add to my metric badger-load of files, to prevent this error without swapping browsers or waiting for an update (since it's already been happening for quite some time).
The error:

Safari Can't Open the Page
Safari can't open the page.  The error is &quot;The operation couldn't be completed.
(kCFErrorDomainCFNetwork error 1.)&quot; (kCFErrorDomainCFNetwork:1)

Some potentially useful information:
macOS Mojave Version 10.14.4  (On a desktop, if that matters.)
Safari Version 12.1 (14607.1.40.1.4)
I was having the same issue with my homepage which is stored locally on my mac. Putting the HTML files in the Applications folder seemed to solve the problem.

I know it's not the best solution but at least I don't get an error anymore when opening a new tab.
