Absolutely no error messages. The only thing my browser says is ERR_CONNECTION_REFUSED, the same thing it says when the server is not running.
I have rebooted several times but no change. I went as far as resetting my NAS to try on a fresh system, no luck. I figured I should check if the service is actually running, but does't seem to be.
Tried installing the package you linked to, stil not working. I guess I'll try replacing btsync_arm, but first: how do I do that?
