Can't connect to Dropbox at all in Pop!_OS 20.04 LTS
Dropbox suddenly can't connect in Pop!_OS 20.04, I can't even login on the website (and strangely, sometimes it takes forever to load). I've already tried an advanced reinstallation, giving access to...
- Hi G_W_H, currently, we can only officially support Ubuntu and Fedora installations of the Dropbox desktop application. Even though your OS is Ubuntu-based, we wouldn't be able to support it directly.
In relation to your issue, there is a possibility that a proxy, VPN, security software, or even ISP/router issues could be restricting traffic to the following Dropbox domains.
Given that the Windows installation works fine, there must be something specific to the Linux installation which could be causing the issue.
I know this problem probably doesn't have a exact solution, but still I would like to read some inputs that could be helpful, if not to solve the issue, to help understand it.
My guess is that it has something to do with the system, something that is blocking this connection, but I am not knowledgeable enough in Linux to figure out this type of stuff myself.
Hi, I know this is a very late addition but I was just installing Dropbox in Pop OS 21.04, having used it fine in 20.04 for a long time, and encountered a problem connecting to the download servers to fetch the daemon as well.
After trying the fetch manually I noticed it was connecting to the IPv6 address for the hostname, so I temporarily disabled IPv6 and the connection worked perfectly after that.
I would guess that your Windows installation already has IPv6 disabled, and that there must be something wrong with the routing or traffic filtering at Dropbox's (or a content provider in between) end... an easy fix anyway!
To temporarily (until next restart) disable IPv6 on Linux you can do this:
sudo sysctl -w net.ipv6.conf.all.disable_ipv6=1 sudo sysctl -w net.ipv6.conf.default.disable_ipv6=1
You can Google for some permanent solutions if this works and you need to keep it going. (I haven't yet tested whether IPv6 is broken for syncing as well, or just for fetching the initial daemon)
Hope this helps!
