Solution

The reason behind the expiry showing up as "invalid" is because the default licenses does not have expiration date associated with them and they are not stored or registered with the online license server.

So with the issuance of show system license command on SRX, the license server does not recognize this license and marks it as 'invalid' or in other words, the invalid expiry means that a valid license is not installed and the SRX only has the free, default licenses.

To fix this issue, make sure your system date and time is set correctly. Some licenses will have a start and end date and if the device clock is showing wrong time, it cannot update the expiry date and time. Hence, it will mark the license as invalid.
