Sync issues while on wifi
Hi everyone I have dropbox not wanting to sync while connected to the wifi, if I swap to mobile data then dropbox syncs. Also same applies if I attempt to connect to any of the Dropbox websites or on...
Hi Glen11, and thanks for posting this on our forum!
After reading your message, it really sounds like the specific network/WiFi you’re connected to is blocking Dropbox for some reason.
Just like our support team suggested, I’d also recommend contacting your ISP, in order to check this. If this wasn’t related to your WiFi, then the issue would persist no matter the network you’re connected to.
I hope this clarifies things a bit.

Dropbox StaffHi lockedbag, thanks for the message.
Do you have any proxy, VPN, firewall, or security software could be restricting traffic to the following Dropbox domains?
Is this a company-managed device by any chance, or is it a personal phone from factory settings?
Hi, thanks for these questions....
It is not a company managed mobile device.
There is no proxy,VPN,etc that I am aware of.
My Laptop connects tot he internet various ways. 1, through Mobile hotspots, 2, through home WIFI, 3, through Work WIFI
1 -I can put my SIM card in my colleagues mobile ( iPhone 😎 and can do anything with DROPBOX
1 - I can put my SIM card in my brand new mobile ( Samsung A22) and no access to DROPBOX
1 - I can put my SIM card in my old mobile ( Samsung J6) and no access to DROPBOX
1 - I can access my friends HUAWEI and can do anything with DROPBOX
2 - My Laptop using my home WIFI ( Vodafone fibre router) has no problems accessing DROPBOX
3 - My Latptop using the work WIFI has no problems accessing DROPBOX ( by the way the office WIFI is off a Vodafone HUAWEI Wireless broadband (mobile network) modem)
Bottom line, when my laptop uses the SAMSUNG hotspot WIFI, dropbox is no longer accessible.
I tried to get SAMSUNG to help - they pointed to DROPBOX....
Hope that helps! 🙂
Hi @lockedbag
We too are seeing exactly the same problem. We too use Vodafone NZ. Ours started on 23 June (similar timing to you). I don't believe it is Dropbox related as we have also tried WeTransfer and see the same issue. We can't upload files to either service. We had been successfully using Dropbox (via API) from these phones for over 6 months before 23 June. It stopped working on 23 June without any warning. It's affecting our 50 phones, so it's not unique to one phone. Interestingly Microsoft OneDrive works fine, so it is just some services.
From our tests the problem exists on managed (Intune) or unmanaged phones (including ones factory reset with nothing else on them), where the phone is Android (we only have Samsung's, but a variety of models), and only on the Vodafone NZ cellular network.
We can take the very same phone, and use it on the 2degrees or Spark networks successfully. And use the original Vodafone SIM in an iPhone and it works. It also works on wifi which is connected to the Vodafone fibre network.
My feeling is that is a timeout issue, as when we open Dropbox in the browser, even before doing an upload, there is great slowness and timeouts when moving between folders.
I have logged calls with Vodafone NZ, but am still awaiting a response.
Did you get a solution / any progress ? It would be good to be in direct contact if possible to share experiences.
Thanks
hi, VFNZ said there were no changes to their network and that the settings in SEIBEL on one phone number ( on iPhone) were exactly the same the other number not working( Samsung).
They said you should contact the phone manufacturer.
Your testing seems way more in-depth than I can perform...especially changing carrier SIMS....well done.
I suspect Vodafone NZ has put in another layer of security and it somehow relates to Android. Perhaps it is looking up some sort of DNS or proxy and it doesn't exist. ( a colon put in the wrong spot in the code)
Let me know how you go, you may have provided them with more data to analyze the situation and you have way more phones so are probably a bigger customer.
Glad you found this thread.

Thanks Paul.
One question - you mentioned you tried a Huawei (presumably using Android) and it worked. If that's the case, my presumption that Android was part of the issue may need to change to Samsung / Voda NZ as the issue. We're going to try and track down a non-Samsung Android tomorrow to test.
I agree, I think there is some obscure network setting somewhere that has been changed. Or there is a piece of network equipment that is using some older standard, and a Samsung or Android update has now stopped it working fully. The difficultly is finding the right person at Vodafone NZ to talk to - we're currently with the mobile team, but my guess is that it is a combination of mobile and the underlying network.
We had thought Chrome might be involved, as there have been a lot of updates recently, but also tried Edge and it too had problems (though it is now based on Chromium).
I'll let you know how we get on.
Cheers
David
