I cannot access Dropbox from any of my accounts, from any location

[Hgadvocate]

I cannot access Dropbox from any of my accounts, from any location (different Wi-Fi), or from any device, whether the app or a web browser. Except from a cellular connection.

Whats the errors? What happens? 

We need a bit more info here. 

[Hgadvocate]

The error is no response. It never connects. When I try with a browser, the Dropbox site won’t load at all. Like when there is no internet connect, except I am connected to the internet for everything else (email, web surfing, etc). Same with app devices - no connection at all.

Have you checked things like firewall and filtering software? LittleSnitch has also been known to do this

[Hgadvocate]

A mini Mac, an iMac, a laptop, a tablet and an iPhone. The firewalls are off. Yet none will connect. Different locations - office, coffee shop, etc. - yeild the same result. Also three different accounts - two free, one subscription. Same thing.

Yet the phone works if you connect via cellular? 

[Hgadvocate]

Correct.

[Mark]

The issue then is down to your ISP and the connection between the ISP / devices (firewall/routers etc.) because as you have shown the devices themselves are able to connect and work via a different internet system.

I go back to my original comment then about making sure that its allowed on things like LittleSnitch etc and checking traceroutes etc. to see where its being blocked.

[Hgadvocate]

I don’t have little snitch or anything like it. Just the native OS firewall which is turned off right now. Do you have a suggestion for how to trace the connection?

We were having the same issue, it looks like it just resolved itself.  Here is the tracert before and after.
