Connecting to hidden wireless network during Parabola installation issues

Has anyone here usccessfully managed this, and if, how?

I followed this: https://michaelheap.com/connecting-to-a-hidden-network-on-arch-linux/

But I still get the "ob for name at domaine failed because the control process exited with error code. See "systemctl status name at domaine" and "journalctl -xe" for details"
