Ok, I left out a step that I did on setup. I downloaded the iso file and created a VM and put opnsense in that. When I determined that a container is better for lower resources I deleted the VM and created a container instead. That maybe messed up the installation. I try to create a container from scratch and see that there is no option to upload an ISO file into a container. You can only specify a container template. So perhaps I should stick with a VM?
