Tailscale IP wont connect

So I have installed a brand new version of the latest Truenas and I installed a HDD, after that I wanted to get an access to the PC from outside so I can watch my films and TV shows when out and about but no matter what I do I can’t get Tailscale to work, I have asked in multiple places and I am getting no luck so I thought I would ask here.

I registered with Tailscale and got my Auth Keys, I loaded up Tailscale on TrueNAS Apps and edited the config file and here are my settings I have changed, Auth Key (got this from Tailscale dashboard) Extra arguments I added --advertise-routes=192.168.0.0/24, Host Network I have ticked, apart from that, thats it and on the tailscale side under machine I edited Route settings and ticked Subnet routes and thats it, I don’t know what I have done wrong so if you have any suggestions please help.
