Webviewer shows Upgrade Browser Message When navigating to Dropbox for Authentication

[MartinL]

Hi

I am trying to create functionality in my FileMaker 19 solution to connect to Dropbox using oAuth2 using the Webviewer.

However when I use the URL 'www.dropbox.com' for Dropbox with or without the necessary URL parameters all I get is a page saying 'Upgrade your browser to use Dropbox' with error code 409!

My machine is Windows 10 with the latest version of Internet Explorer (20H2), I also have the latest versions of Firefox, Edge and Chrome and have installed the latest FileMaker V19 update as well.

Also I have checked my machine for any outstanding updates and there are none.

Even my previous functionality for Xero and Quickbookswhich I successfully tested some months ago is no longer working and gives the same error message.

Please can someone tell me how I am supposed to upgrade Internet Explorer and to what or how to  change the default browser used by the Webviewer, I have search the internet for answers but as yet I have had no luck.

Thanks in advance

Do you use MBS FileMaker Plugin?

You could try the WebView.PostURL to pretend you are a different bowser than IE.
