I can't connect my AirTag to my iPhone

I am having trouble connecting my air tag. I have gone through all the steps and settings that are required and yet it won't connect. I even bought different air tags and I was not able to connect those either. My bluetooth and wifi are on. Location services are on--while using Find my app and designated as precise. I have installed the new IOS for my phone 26.1 and reset the various AirTags multiple times. When I choose to add an airtime and put it close to my phone, the never finds it.
