It’s not SharePoint. It’s the URL.
We’ve all typed in the wrong URL, right? Or maybe used an old URL bookmark that wasn’t valid anymore? I suppose this type of issue could be labeled "user error" but I’ve never liked that phrase and that really doesn’t describe the problem accurately anyway.
How did the issue present itself? à "Internet Explorer cannot display the webpage"
Isolating the issue à Confirmed the URL the user was trying to access.
Root Cause à User accidentally typed in wrong URL.
Resolution à Use the correct URL. J
So here’s a quick tip as it relates to this… This particular issue can make you think something worse is going on, so it’s a good idea to check the URL before you start researching. (Yes, I spent several hours one day thinking there was a bigger problem, only to realize it was just a typo in the URL!)
