The port is a B key m.2, while the ssd is an M key m.2

B keys are used in SATA m.2 ssds, while M keys are pcie nvme m.2 ssds. You bought an nvme m.2 ssd, but needed a sata m.2 ssd.

(You can tell by how there are 28 pins on that side of the port, and 29 on the ssd. That matches b and m keys, respectively)
