Ultimaker 3 install

I am following the instructions to install Cloud Printing on an Ultimaker 3. When running the custom link through SSH, the files download but there is an error on installation: mv: cannot stat ‘/tmp/stuff.bin’: No such file or directory

The option to allow or deny access does not come up on the Ultimaker 3 screen afterwords.

The ultimaker is running firmware 3.7.7.20170627

Help!

Hello.

If you have ‘/tmp/stuff.bin’ in console then you used client installation command after timeout (you have about ten minutes to use command after generating for only one printer). Please reopen u3 client download page again (https://cloud.3dprinteros.com/download/u3) and execute command one more time on U3 ssh
