Cannot link Dropbox to account (Linux)

Explorer | Level 4

I have been using Dropbox on a laptop running Linux Mint 19 for a couple of years now.

Until a few days ago it was working. The, for some reason, the syncing stopped working with no error message but seemed stuck uploading.

I uninstalled and resinstalled Dropbox with latest .deb install available as an attempt to solve the problem.

Now, Dropbox is simply not connected to my account any more but I cannot find how to connect it. Logging-in to the web site using a web browser does not suffice and there is no button in the Preferences interface to that.

How the hell can I link Dropbox to my account ?

Hi @HappyHugger,

Dropbox application tries link to account at launch time and that's not possible later. If for some reason linking fails, you have to restart the application. Make sure your default browser runs and you are logged in your Dropbox account already, before application restart. There are known bugs related to launching new authentication browser window sometimes. If you can't link the application to your account still, a clear console variant could be a workaround. In such a case execute following commands in a terminal:

dropbox stop
ssh $USER@localhost
dropbox start

"ssh" will ask for your local user password (not the Dropbox one). After the last command a web link will comes up in the terminal. Click on it will open an authentication browser window, where you can link your application. After successful link, you can use the application as usual further.

Hope this helps.

Ok.

I managed to connect : instead of using my home's wifi, I used the 4G connection of my mobile phone.

Same assessment for the initial problem that had led me to reinstall Dropbox : when I am connected using the 4G of my mobile phone, syncing works ; when I use the wifi, it stays stuck.

It is not a computer's firewall problem (I disabled it).

Seems you have a network problem (especially the WiFi). I can't say what exactly goes wrong, but you could check. Check if you have proper access to different domains in use (using 'ping', for example). Important domains are: www.dropbox.com api.dropboxapi.com content.dropboxapi.com notify.dropboxapi.com See if the domains could be resolved (i.e. your DNS works) and servers give response (i.e. the connection is possible). Make this check while you're using your WiFi. Once the application got linked yet (using 4G), is the issue persist when switch to WiFi?

Hello and thanks for youu suggestions.

I am still in the same situation : when connected by wifi, Dropbox gets stuck trying to connect. If I use 4G, connecting and updating works smoothy but when I switch back to wifi, it gets stuck again (updating).

While connected by wifi,  have pinged the four domains  you mentionned without any trouble.

Is there some kind of debug mode or logs to Dropbox ?

Good question!!! Very good one!

The only user accessible log match the pattern "/tmp/dropbox-*". It contains only part of initial loadings log, unfortunately, nothing more - unusable in fact. There seems to be other log(s) in "~/.dropbox/logs", but in encrypted form, so inaccessible for user (probably only available for Dropbox staff). Many other queries for same (i.e. log availability) are set, but Dropbox keeps quiet. Such thing could helps in many troubleshooting steps, like in your case.

Let's hope someday Dropbox will add such possibility.  You shouldn't have to rely too much.

Thanks for the update, @HappyHugger!

It definitely sounds like there is a proxy, VPN, firewall, security software, or even ISP/router issues that could be restricting traffic to the following Dropbox domains.

Since it’s working on 4G, there is no issue with the Dropbox app itself, but something related to your hardware network connection. Is there a firewall or blacklisting directly on the router?

If need be, you might need to check with the ISP for more help on this matter.

Let me know how it goes!

Hello.

 

I am still stuck.

I tried connecting to the modem using an ethernet cable instead of wifi : same behaviour.

I had a look at the modem's admin interface to see if there was any firewall / filtering rule that could explain this : I did not find anything.

The problem is also that, in addition to not having logs, I don't know exactly what connections Dropbox use. To which domain / IP ? WHich ports ?

The last thing I can suggest to check if it is related to your internet connection is, if possible, to use a different modem entirely.

If that doesn’t work, then your ISP is blocking connections to the Dropbox servers.

Blaming the ISP would be an easy solution but the truth is that I currently have no evidence to support this, due to the absence of logs or debug mode with Dropbox. Besides, it's the same ISP that provides me the 4G connection and Dropbox works fine with it !

 

I cannot believe that Dropbox has no way of debugging their software. Debug logs are software development 101.
