Error (403) in Dropbox When you Login: How to Fix the Problem

Dropbox is one of the top cloud storage service providers trusted by millions of people and companies. However, it seems that their website has issues with most browsers and especially with Google Chrome and Firefox. The famous Error (403) stops users to log in to their accounts and manage their files.

The big problem is that when you check your login details, you will find them correct. However, you can’t log in again to your account, and the site keeps getting the forbidden error, every time you want to access it.

These issues happen in Windows 7, or 8, 10, or the latest Windows phones, and mobile phones in general. But, the problem can also happen with iOS and other operating systems.

The problem is your web browser cookie settings or the Dropbox cookies themselves. To solve and fix the problem, you just need to delete the Dropbox cookies from your browser, and you will access your account again, this will work in the majority of cases.

How to delete Dropbox cookies from your browser?

For Google Chrome, click the options menu at the top right corner of your browser, and choose “Settings”, as the next screenshot.

Finally, visit Dropbox again, and you will be able to log in this time. It’s a cookie issue and you need to clear your browser data the next time, or simply, use this method to remove the cookies manually, you will need the same thing every time you get an error.

You can read how to remove the website cookies in Firefox. On the other side, for Windows Phone, read this page to delete cookies and browser cache.

If you’re using Safari, then, the safest and easiest way is to clear all the website data, including cookies. For that, click “Safari” at the top left area of your browser, just next to the Apple logo. Then, click on the fourth option called “Clear history and website data”. Finally, close and open the browser again and try to login to your Dropbox account.

As you can see, it’s just a cookie problem that makes people out of their accounts during hours, or even, days, if they never want to clean their browser data. This will not fix all the future problems, but you need to repeat the same step every time you have issues logging in to Dropbox.

They should work on this problem and fix it as soon as possible. People who save important data and backups in their accounts, and need to have access all the time without errors.

If you’ve solved your problem in another browser, especially, on smartphones, please share your ideas and your comment and help others who have the same issues. Dropbox is great, but sometimes, things can look out of control for users who care about their sensitive data.

  1. As of today 04/03/2020 I cannot sign in to Dropbox account when using my Kindle Fire Android System. My sign in password has not changed in quite some time. The message I’m getting is Unknown Error Sign In Failed contact Dropbox Support. I have uninstalled the Dropbox Twice and reinstalled it twice all without success when signing in. However I can go to and login successfully there without any problems. I think there is problem with the Dropbox App via my Kindle Fire. This is very inconvenient for me please create a solution or fix it asap.

    Thanks you,
