Network MNGR disconnects from hidden wifi network upon reboot

I recently disabled SSID broadcasting on my router and set up a static IP address for my laptop and now when I reboot my computer I don't have wifi connectivity and I have to manually re-add and activate the connection with nmcli to get it working. before I reconnect I see that Network Manager is enabled and running and it's instance of wpa_supplicant is running. Also I have the boxes for "automatically connect" and "available to all users" checked on the connection settings in the applet. After researching, I can't seem to find out why it's not automatically connecting. I don't have any conflicting network services running. I'll post the output of journalctl -u NetworkManager -b as well as the list of enabled and running services before I connect to the network with nmcli.

What about this:

I don't actually know what the third column means though (I'm using an older version of systemd) so I may be mistaken here.

No need for grep anyway:

systemctl list-unit-files --state=enabled

And I presume the connection works as expected if you don't "hide" it?

Off-topic for this thread but "hiding" your SSID does not improve security in any meaningful way.
