Sign in - There was a problem completing this request (Android Device)

Explorer | Level 3

I can't sign in to dropbox on my Android device. I can sign in through the browser no problem, but on Android App embeded browser(WebView) I always get the message "problem completing request" as shown in the attached screenshot(In April, it was no problem). I am using Android 8.0. I had test on Macbook (Chrome & Safari) successfully.

response_type=code&
redirect_uri=https://www.localhost.com&

Thanks for sharing this. First, please note that you should not use a webview for the Dropbox app authorization flow, per our /oauth2/authorize documentation

As for the issue, it looks like it's because it's using an old browser engine, e.g., an old version of Webkit. Unfortunately that is not officially supported by the Dropbox web site

Old browsers/engines like this are not officially supported by Dropbox and so may be prone to issues as the Dropbox web site is updated. (This is one of the reasons for our policy prohibiting webviews; we've found webviews are more prone to compatibility issues like this.) For example, it's likely that there's some JavaScript error or incompatibility when attempting to access the Dropbox web site form in this webview, causing the sign in form to fail, as you're seeing. 

Since that isn't supported, I'm afraid we can't offer fixes for issues like this. I recommend you instead upgrade to a supported system browser to resolve this.

Hi @johnWang, thanks for posting today!

 

It sounds like there might be an issue with the connection itself. Could you try switching browsers to see if this helps? 

 

Otherwise, use incognito/private browsing mode without any extensions running, clearing your cache and even resetting your browser entirely. 

 

If it still doesn't work, there is a possibility that a proxy, VPN, firewall, security software, or even ISP/router issues that could be restricting traffic to the following Dropbox domains.

 

Let me know how it goes!

client_idxxxxxxxxxx&
response_type=code&
redirect_uri=https://www.localhost.com&
state=xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

 

 But now is fail (Error message : There was a problem completing this request) when I login Dropbox account & password for testing. 

In April, this function was work successfully.

 

I had test some case

(1) My App with Android Embedded browser(WebView) to open url and login Dropbox account ========> Fail

(2) Android device with original browser to open url and login Dropbox account ========> Success

(3) Macbook with browser (Safari & Chrome) to open url and login Dropbox account ========> Success

Hi @Greg-DB , thanks your reply & support.

 

I find the issue that I set wrong user agent.
