Error 404 when trying to login from multiple browsers.

I have had a problem logging into my Dropbox accounts in the last couple of weeks. Every time I try to login, the login page flashes up briefly and then I get the dreaded 404 page. I have tried logging in from different browsers and repetitively trying to login from the list on the 404 page, but often nothing but closing the browser down and re-opening it works. I didn't have that problem before so I don't understand why I have it now.

Hi @k3pard03, let's jump right into this!

Interesting. Have you tried clearing your browser's cache, by any chance just to exclude that as a possibility? Does that happen with all the browsers you've tried?

Additionally, do you have any proxy, VPN, or even ISP/router restrictions could be restricting traffic to the Dropbox domains?

Let me know more, and we'll take it from there!

I've cleared the cache and it doesn't fix the problem past the first time I log in (in Chrome). As soon as I log out and try to log in again, I get Error 404. There doesn't seem to be a problem with Edge. I think it is to do with Dropbox autofilling the last username (somehow). I have cleared autofill, turned autofill off, unticked "remember me" and still get Error 404.

Hi @k3pard03, could you send me a screenshot of the error you get -without showing any of your personal info-?

Several of my team members and I have also being having this problem the past few weeks. We've found that the problem is Google is forcing the page to move to a "sign in with Google" option, but we use Outlook email addresses to sign in so that the company can control what happens when team members leave.

I've received this error, many of my team members have received this error.

Hi @SoundTranscripts, do you have any kind of password manager that tries to autoogin onto the Dropbox site, or does your group use any kind of SSO to access your accounts?

SoundTranscripts

Hey @Jay, we use Lastpass. I also noticed that it doesn't happen when I use Firefox to log in to the exact same account using Lastpass. I think it may be a Chrome-specific issue.

Jay

After a brief search, there is a feature for Chrome called Auto Sign-in, which uses your Google profile on the top right to login, and it could even be a group policy from IT.

It's possible this might be related to what you're experiencing. While I can't provide support on that feature, perhaps the information I provided above might help out a little.

After some troubleshooting (because I'm the technology coordinator for my company), I think I have a workaround. The problem does NOT happen in FF when using Lastpass to log in to Dropbox.

I think a recent-ish update in Chrome is what started this. My recommendation to anyone who is having problems getting into Dropbox using Chrome is to temporarily log out of your Chrome browser account. (Make sure you remember your password before you do!)

Then log in to Dropbox using the email+password method, then you can log back in to your Chrome account on your browser.

I'm off to test this with my team. Fingers crossed this fixes it for everybody! I can't tell you WHY it does this, but hopefully, it will be the fix needed.

The screenshot is the same as shared by SoundTranscripts. I have also tried logging in and out of the account I use for Chrome, but that hasn't worked. Logging into the Dropbox community works fine, which makes no sense because the login is the same as for Dropbox itself. I can then get to my folders by simply clicking on the Dropbox icon. If I then log out, I get the same 404 Error when I try to login from the main Dropbox website.

I cleared my cache several times and do not have any of the other restrictions. I have also disabled autofill from Chrome and Lastpass, but I still have the error problem. The only way I can avoid the error is if I switch to the main Dropbox site from the Community. That is, I can login to the Community with no problem from any browser but I can't login to my Dropbox folders via Chrome (because it autofills a user name and immediately gives the error). If I clear the cache and wipe out cookies, I can login directly to Dropbox, but only once. This isn't a problem in Edge.

Hey @k3pard03, could you let us know the version of the web browser you're using so that we can investigate further?

k3pard03

Version 117.0.5938.63 (Official Build) (64-bit). I'm still having to login to the community and then go to Dropbox or I get the 404 error.

Nancy

Hi @k3pard03! Are you seeing this error message as soon as http://dropbox.com/login loads, or does it appear after you’ve entered your email address and password?

Besides that, can we log a ticket for you and email you here?

k3pard03

The email address auto-fills unless I use something like https://www.dropbox.com/login?cont=%2Fh to log in. However, if I try to use that from LastPass,

it auto-fills the email address but doesn't give an option for password and then goes straight to 404. This happens even though I don't have auto-fill enabled in LastPass. If I log out (after logging into the Community and then going to main Dropbox), sometimes it auto-fills and fails and other times it doesn't auto-fill.

I can (obviously) work round the auto-fill problem by using Firefox or logging into the Community, but it would be good to understand why the 404 error is happening, as it didn't until shortly before I reported it. Up until that time, I had no problems logging into Dropbox, from LastPass or any browser on any device I have.

Thanks for the info, in order to look into this matter in more detail, would it be possible to reach out to the email associated with your forum profile?

k3pard03

Yes, please use the email associated with my forum profile.

Jay

Thanks, I've sent you an email, please could you reply to it as soon as possible.

Hi all,

I just wanted to provide an overview on this report:

If you can login without problems when you are not using Last Pass, the issue might be related to Chrome and Last Pass.

Our team has looked into this, and we haven't identified an issue (at our end) at this moment.

Let us know if you have any other insights,

Thanks,

Sam
