Unable to install bindings from Paper UI


I just installed openhab 2.1 over a 2.0 installation (tried upgrade but didn’t work). When trying to install the trådfri binding in Paper UI, the circle keeps spinning ang i get a 504 Gateway timeout error. I installed the openhab-addons and changed ownership of the openhab files to openhab:openhab. What am I missing? Package in addons.cfg is “standard”

EDIT: 2 seconds after publishing this, I added the tradfri into addons.cfg, this seems to do the trick…
