err_connection_refused

[Nosbags]

Can’t seem to connect to Dropbox at all using multiple different browsers and in private /incognito mode. Keeps saying refuses to connect.
Have added Dropbox.com to trusted sites in settings, uninstalled and reinstalled the Dropbox program and browsers. Have also made sure no proxy settings are active along with making sure the program is allowed access. NOTHING WORKS!!!

So, i came here after days of searching the solving of this problem. I had message: 

ERR_CONNECTION_TIMED_OUT

Nothing helped (hosts, reinstall, network settings reset, switch off extentions, cleaning cookies, incognito mode etc and etc ) except one thing: 

go to router settings, set there another DNS. What's interesting, popular google DNS did'nt helped, but Cloudflare's worked fine and i finally is able to use dropbox again. Update: later i tried again google's dns (8.8.8.8 and 8.8.4.4) and it worked at that moment. Advice: after changing dns wait for 1-2 minutes and only then try to access Dropbox.

So two steps:

1) Go to router (if you use it), change DNS settings to  1.1.1.1 and 1.0.0.1 (alternate). 

2) Also did the same in the Properties of Network adapter (tcp/ipv4 section). like on the bottom screenshot: 

So in my case it is something with default dns from my Internet provider (dropbox stopped working one day without any changes in the system). Manually changing DNS helped. Maybe it will help you too. Try. You can also try to use another public DNS servers, just google them. Because dropbox can work with some well or don't work. i'm just switching different dns till i get possibility to upload/ download files. (sometimes upload process starts from few tries. But still, it is now working overall)

I had the same issue. Turned out I set up OpenDNS some time ago, reverted to automatic in the IP v4 settings - now all is fine.
