Dropbox web keeps dropping uploads after a few minutes saying I have no internet

Ok...so I decided to go another route and break up my files into a few zips so my ISP won't complain about size...but as I was doing that, I saw a pop up from drop box saying upload is complete with a share link available.
However, the same error messages are still displayed saying the upload is currently paused.
So something is buggy about all of this.
I'm using the latest FireFox version but also because as I was searching I saw someone say to try using the desktop app.
So I did and I don't see the point in that since all it does is add a few options when right clicking a file - In the end, still using the browser to upload anyway.

As another note...it took about a minute to get the link which seems long since the files have already been uploaded.

Hi Jaiy, thanks for posting on our Community. 

Are you experiencing the same behavior on different browsers, or incognito mode? 

If yes, I’d like a screenshot of the error you see, as well as the brown box that keeps appearing. 

Keep me in the loop.

Hi...still having issues again today.
45MB file uploading. Fails within a minute or two mentioning about internet connection.
My internet connection is stable, I upload regularly about the same file sizes to other servers on the same browser.
I've tried different browsers with DropBox and tried Incognito mode and still the same issue.
Here is a screenshot of todays issue.

Hi @Jaiy, thanks for the info, do you have any proxy, VPN, firewall, security software, or even ISP/router settings that could be restricting traffic to the following Dropbox domains?

Same issue for me, for at least a month now, on Safari.  No VPN/firewall/etc.  My workaround is that I hit cancel in the upload queue, and then click retry.  Sometimes the same thing happens, sometimes it works.  Very annoying.  As of today, I'm trying it with Chrome, and that seems to be stable, whereas Safari continues to fail over and over, and even my previous workaround isn't working at all.

Since I haven't seen a resolution in this discussion, I'll post and say I have the same problem with synching from a Windows 10 machine (not a Mac!) on both the desktop app and through the website via the browser (I've tried Chrome, Firefox, and Opera). I've had problems with files of all sizes--nothing bigger than a couple hundred MB--but currently, I'm running into the "Uploads paused" brown banner with a message near the filename "Paused - no internet" for 469K or 1015K PDFs!

I don't have any VPNs or firewalls that traffic is going through at home. We had to switch to cable internet (Xfinity Comcast) which shouldn't be restricting traffic to Dropbox domains. It has slower upload speeds, but testing shows it's typically ~20-30 Mbits/sec so a megabyte-sized file should not be an issue.

In these situations when the upload has "paused", I'll cancel and retry. Sometimes I'll walk away from the computer and eventually the file gets synch'ed up perhaps hours later. But it's pretty frustrating to see that 20% of a 1 MB file has uploaded after 1 min, but then the browser is stuck on the rest of the minuscule file before Dropbox gives up with the brown banner of death:

I regularly upload gigabyte-sized videos to YouTube without an issue with my current network configuration. Is there something fundamentally wrong with how Dropbox is talking to its servers from my computer?

Hi kachunyu! I’m sorry to hear this is happening.

You may have already tried this, but do you notice the same issue when uploading files to our website from an incognito window instead?

As for the desktop app, are you seeing the exact same error message stating that you don’t have an internet connection?

Hi Nancy ,
I get the same problem when I switch to Incognito mode on Chrome. Here it is stuck trying to upload a 1.1 Mb file:

I get a different problem when I use the Dropbox app on Windows. I can open up my Dropbox folders in the Windows Explorer, and copy files from another Windows Explorer folder. This can often work, but I also get problems where I tell Dropbox to "Sync now" with the servers via a drop-down menu link:

In this case the syncing can also take extremely long. At least it runs in the background when I do this, so that eventually it gets uploaded. But sometimes it's taking too long for my immediate nneds, so I switch to the browser version ... and then I switch again if what I'm using starts to slow down ...

Hi kachunyu, let me also jump in there!

So it seems like we have two points here: one with how the website uploads content and one with the app, specifically when you use the sync now function. 

As a first step, would it be possible to try uploading content using a different network/connection, to see if you get those same results again?

Also, when did this behavior first appear?

Can you also hover your mouse over the little Dropbox icon on your task bar, next to your WiFi and clarify the version of the app that you're using?
