Error Connection Timed out
All the Windows PCs on my network this morning, regardless of version of Windows receive an ERR_CONNECTION_TIMED_OUT when trying to access www.dropbox.com. The OSX machines are fine. All receive IP (Address, DNS) info from DHCP server, all use same firewall that has no rules blocking outbound connections. I tried using Google DNS servers, same result. Does not seem to be a DNS issue as a ping to Dropbox from those PCs return the IP address correctly.
It is obviously something on my network, but why only the Windows machines?

To further clarify. I am experiencing the connection issue when I attempt to download files off of the web client via PC. I am to see that the files are present but experience the connection issue during download. It states "waiting for bolt.dropbox.com" before the connection error appears. However, via the dropbox android app I have no issues. My ISP is Continuum Online Services Ltd.
I'm in Toronto and also having the same issue, only a problem from windows computers but OSX works fine. ISP is Beanfield

Interesting that all 3 reports here, Data-SoilOptix, GrandLuc and I are from Canada.

Problem was intermittent late yesterday, but down again this morning for my Windows machines. This is really inconvenient for us, we rely on DropBox for our daily workflow.
I have a ticket open with support, but no response yet. This can't be easy to track down.
I suspect there is a something in the dropbox infrastructure that is rejecting traffic originating from Windows, maybe some packet structure or packet content specific to the Windows networking stack. When testing from my network I am able to Telnet www.dropbox.com 443 from OSX but not from Windows (CONNECT FAILED).

I have the same problem connecting to www.dropbox.com, dropbox.com (but not help.dropbox.com strangely) on Windows systems. Also from Canada (Quebec)
- Laptop Win10 updated, 3rd party AV/FW: timing out as above.
- Desktop Win7 updated, 3rd party AV/FW: timing out as above.
- Tablet Win10 updated, no 3rd party AV/FW: timing out as above.
- Tablet Android: no problem.
- Virtual machine, Linux Mint (with dedicated NIC): no problem.
(Note: disabling 3rd party AV/FW above doesn't solve the problem)
Exception: Virtual machine, Win7, not updated since 2016 (testing purposes), on dedicated NIC: no problem connecting.
A couple of days ago, I got a recent update on both Win10 systems, and applied april updates on desktop Win7... coincidence?
/Edit: I'm a home user on DSL, not with "fibrenoire"
GrandDuc I am also expriencing issues connecting to dropbox. On both browser or the desktop client on windows 10. I am also on Fibrenoire. I have no issue what so ever if i connect through my iphone hotspot (Bell Network). I also hardcode myself to my backup link bypassing fibrenoire network (also on Bell network) and i can connect successfully. Have you opened a ticket with fibrenoire to check if they had anything going on with their routing or other network issue?

Yes, I had a ticket open with them yesterday, they found nothing on their network. When it seemed to have returned to normal late in the afternoon I closed that ticket, but the return of service was temporary at best.
I suspect it has more to do with the network path to DropBox infrastructure and the routers/firewall I am hitting via FibreNoire. My Windows machine at home on Videotron works fine, I tested yesterday.
