I followed some instructions and unstalled it to install it again and since this moment, it's impossible to connect the dropbox.

I tried to use the Off line version, but same results, checked the fire wall, time & date, ...

Thank you for your assistance.

Something on your computer or network is blocking Dropbox from connecting. You need to determine what that is. Some antivirus packages have been known to cause this as well, so temporarily disable your antivirus and try again. Are you able to sign in to the Dropbox website or is that being blocked as well?

I am using kaspersky as anti virus. I desactivated it but still the same issue. I can have access online.

The issue is only with the apps. I push the button "connect" to fill my mail / password but a message is coming "you are offline, check your network". 

All was working perfectly few days before with the same configuration.

Hey @Arthael_Sn, have you tried restarting your computer after disabling your antivirus, to see if that helps?

 

If it doesn't, you can try our offline installer as well.

I read your message where you said you DID try the offline version and that didn't work. 

Sometimes Windows OS puts in a firewall rule that bans apps like Dropbox. I'm not sure if Windows 11 put something in their code to ban disabling their firewall completely or not, but I would try disabling Window's firewall as well. Plus, you might need to get Windows Tech involved to see if Windows OS11 is doing the blocking.  

 

1. Disable all firewalls and Anti-virus. 

2. Delete all versions of dropbox.

3. Reboot computer. 

4. Check to see that Windows Firewall is still Off.

5. Check to see that anti-virus is still off. 

6.  Clear all cookies and cache in browser (just in case). 

7. Redownload Dropbox app.

8. Attempt to install it.

9. If it still does not work, bring Computer to Windows IT and ask them why their code is blocking Dropbox.

10. Keep in mind that this answer assumes you are not living in a country whose government decided to arbitrarily block Dropbox. 

 

The other issue might be a Windows 11 update that broke apps ability to recognize that you are connected in any shape or form. I would do a research online to see if anyone else has had this issue but did not post here to dropbox. 

signed Windows user who has had Windows Firewall issue before, after turning off antivirus software. 

This is all the ideas I have. Sorry!

Hi @minuscustserv, happy Friday! 

 

The Dropbox client uses SSL to establish a secure connection to our servers. To ensure this is working properly, your system time should be correct and your security applications should allow Dropbox to connect. Can you check this article? 

 

Also, since you have an antivirus and/or firewall running, make sure you do the following:


- Allow "Dropbox" (or "Dropbox.exe") to access ports 80 (HTTP) and 443 (HTTPS).
- Add dropbox.com to the list of approved sites (white list) and make sure it is not on a black list.
- In general, you need to allow *.dropbox.com and *.getdropbox.com to access all the hosts in our domain, since our IPs are constantly changing you need to approve/unblock by domain.
- Some antivirus have special features that scan SSL traffic, please review your vendor's documentation and make sure you exclude Dropbox from the list.
- Some firewalls also act as proxies for your computer, so you might need to add them in the proxies Preferences panel to correctly connect.
