Dropbox connecting problems

I'm having problems connecting my Ipad to my dropbox account. On my pc and on my android device everything is working fine.

My files weren't updating and I couldn't unlink my Ipad. So I removed the app and installed again. When I try to login it says I can't connect, maybe I'm having internet connection problems, but everything is working fine, I have an internet connection. Also I tried to login via Safari on the Ipad and I can't seem to login there either.
