I have this same problem. and error. The link provided above is since broken..
Can anyone help? I am trying to add license key Manually on an SRX which is not connected to the internet an it throws me the error mentioned above...
May I also ask, is this (JUNOS532630) part of the Key as well that should be entered? or should I start from the "giberrish" set of characters i.e (unktzr uyknnp etc )???
