Error Connection Timed out

[GrandDuc]

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?

yep, ok here too, for now.

Curious to know what was the problem.

[GrandDuc]

Yup, working here as well as of now

Hey peeps! Thanks for checking back in here and glad to hear that the issue seems to be resolved for you. 

If the behavior persists for you though, don’t hesitate to give me a nudge and I’ll make sure to get back to you as soon as possible. Thank you!

I'm having this issue now on all our Windows pcs. The app on the computers just stays stuck at "Connecting." I've bypassed our firewall and that did not resolve the issue.

Hi @ITech5401; I'm sorry for the delayed reply. 

If you're still having issues, apart from the firewall, have you made sure that there's no antivirus or perhaps a VPN/proxy setting that might be causing this?
