I can't login using the web unless I use the Tor browser or a VPN on another browser.
Without the VPN, I have tried Chrome, Firefox and Opera browsers and each time I attempt to login, I am redirected to the dropbox sign up page. There is no error message. I have attempted to login using a private browser (no extensions) and with virus protection switched off and I still can't login.
For some reason I can only login on the web using a VPN.
I can access dropbox via my phone (android) without a VPN. When I gain access using my phone I am using wifi. The same connection I use when I can't login on the web. I can also gain access using the Windows app.
