Can't connect to any apple servers, third party apps have trouble connecting
Just found a solution to this after a call with Apple. Simply unchecking &quot;Auto Proxy Discovery&quot; did the trick.
Just go into System Preferences &gt; Network &gt; Wifi &gt; Advanced &gt; Proxies &gt; and uncheck &quot;Auto Proxy Discovery&quot;.
Seeing as you posted this 3 months ago I'm sure you found a solution, but surprisingly I couldn't find an answer to this anywhere so I thought I'd post for anybody else with this problem.
