Safari, Chrome, and DuckGoDuck say: can't open page because the address is invalid

After the latest iOS update to 18.0.1 I cannot open any webpage on Safari, Chrome, or Duckgoduck. The message that appears on screen is: "Safari can't open the page because the address is invalid." The same with Chrome and DuckGoDuck.

I have restarted and followed all the instructions to a T at least three times. I am able to get my email, but cannot get on the net. No other reasons given and customer service is closed... any suggestions. If site repairs were happening shouldn't they be notifying customers on other devices. My computer and iPhone both are online...
