I just upgraded to ownCloud 10.x and installed the new app for Dropbox API v2 support.
I followed the instructions to set the whole thing up, but the "grant access" button does nothing and the little square on the left-hand side stays red - pretty much the exact same problem as described in the comments here.
Hello! It did not work for me. By entering the correct Dropbox API data and then clicking the "Allow Access" button I'm redirected to the Dropbox page to authorize access. After allowing access when returning to the Owncloud installation the square remains red.
Well, maybe I am doing something wrong, down to the basics (and for whom does not have english as his primary language), for "path to your ownclod" We can assume that it is the FQDN of the server right? Is there any problem if the server is behind NAT and using an external port other tan 443 and redirecting it throught NAT?
I don't think there should be any issue with that, as long as that redirect url is reachable from the client/pc where you are performing the oauth flow.
For example, I am issuing the request against my local test instance and have this url in dropbox: http://localhost:9080/owncloud/index.php/settings/admin?sectionid=storage
Note: localhost is a special url for dropbox and allows for using http. When using a different FQDN than localhost, dropbox requires https. So whatever your port number is, it must be the ssl terminated endpoint of your server
I am not quite sure - if you can test with a different instance or with a quick setup via localhost (docker?) that can confirm
I have tried to reproduce the mentioned issue here for quite some time and I noticed that sometimes during c+p from the dropbox website, extra spaces are copied/created. That's the reason why I mentioned to ensure that when copy+pasting no extra characters are copied.
I spoketh too soon. I'm having serious sync-problems with the desktop client on my CentOS7-machine. Also httpd seems to crash on the OC-server (running CentOS6), requiring a daemon restart. I'm disabling the Dropbox app for now.
