Fix 1: Clear Chrome Cache

The most common reason for “ refused to connect” error is corrupt cookies inside your browser cache.

PRO Tip: Clearing your chrome cache after a while helps improve your chrome speed and free up your hard drive space. At times, chrome can save a cache of 5 to 10GB worth of files which drastically slows down your chrome browser. So it’s always a great idea to clear your chrome cache after a few months.

How to Clear Chrome Cache:

  1. On your computer, open Chrome.
  2. At the top right, click More More.
  3. Click More tools > Clear browsing data.
  4. At the top, choose a time range. To delete everything, select All time.
  5. Next to “Cookies and other site data” and “Cached images and files,” check the boxes.
  6. Click Clear data.

Fix 2: Try Incognito Mode

It’s not a fix but more like a way around if you don’t want to clear your browser cache. Clearing the browser cache means you must log into all accounts again.

If you want to avoid logging in again, you can try opening your file in incognito mode.

You can open a new incognito tab using the keyboard shortcut CMD+Shift+N (Ctrl+Sift+N for windows).


  1. On your computer, open Chrome.
  2. At the top right, click More More.
  3. Click New Incognito Window
