can't use safari when off wifi, getting error of "blocked by 'primary'"

Everytime my iphone 12 is off of wifi, I find that my phone is unable to connect to safari to search for anything. Each time I recieve the error of "blocked by 'primary'" and I am unable to search previous websites or previously opened tabs. I have cleared my cookies and data, and have restarted my phone multiple times and still receive this error. All other cellular data using apps still work, just not safari. I have checked that cellular data is on, as well as checked that my VPN is off (I have even removed it from my phone) and still get this error. My carrier is T-Mobile if this is helpful information.
