GS308E Not Discovered by Switch Discovery Tool

Both the Netgear Switch Discovery Tool (NSDT) as well as the Insight app depend on a transparent L2 network between the computer operating the NSDT resp. the Insight App. in case the Plus switch does not receive an IP config from the DHCP server, it will fall-back to the default 192.168.0.239.
This is a just a simple Plus switch, and has no Insight Cloud Management features. This is why it can't be discovered using the cloud capabilities we have on the Insight managed devices.
Nowhere in the NETGEAR 5-Port and 8-Port Gigabit Ethernet Smart Managed Plus SOHO Switch Model GS305E and GS308E Installation Guide it's stated that the switch can be hidden behind a firewall (from the workstation or mobile app view) and remaining discoverable.

The GS308E connected through to the firewalls but couldn't reach internet. Switch Discovery Tool cannot find the address. Then I clicked the (?) gadget on Netgear Switch Discovery Tool and suddenly was miraculously connected to Netgear website.
Nope. The discovery is a pure LAN local L2 process, it does not require the Plus switch to reach the Internet or whatever.

Unless this goofy device is rigged not to connect until you visit the Netgear website, I suspect that I was waiting for switch to time out failing to get a DHCP address, as the switch is not showing up among DHCP leases.
There is no such feature is requiring any outbound connection. In case there is no network connection to your LAN DHCP server, these devices can fallback to the default IP - in case this is outside of your usual LAN IP subnet, it's obvious it can't be reached beyond the pure L2 discovery.

Magically I am connected now, but will it work tomorrow? Why can't the switch discovery tool find the address of the device? (I'm guessing it failed to get an address from DHCP. Why?)
About the only reason it won't get a valid IP config from your LAN DHCP server is not reachable because if there was no connection or the DHCP was not responding.
Note: This is a Plus switch, in no aspect it's making a Managed Switch. So a moderator will have to move your post to the Plus And Smart Switches Forum Discuss Smart Switches (T) and Plus Switches (E), including Local and Remote Management
Worth adding a note here:
The initial GS308E (not the newer version designated as GS308Ev4) and probably other earlier GS108E (v1...v3) or the GS105E (v1, except of the GS105Ev2) can't be discovered by the current Netgear Discovery Tool (different from the earlier Netgear Switch Discovery Tool (basing on the legacy L2 Netgear Switch Discovery Protocol) since this requires the switch to be connected to the same IPv4 subnet, depending on the presence of the SSDP discovery protocol.
What remains possible is using the Netgear Insight App, where the L2 NSDP discovery seems to be integrated - but just for the pure discovery on the LAN or WLAN.
Hope this helps one or the other future reader.
