Any solutions?

I'm guessing you have a very old version of the tigris package installed given that it is trying to download over http rather than https. Try re-installing the package and running the code again.

Latest version of tigris is installed but the same error appears. I removed and reinstalled tigris package. Any ideas?

It's possible that census.gov is blocked in your location or by your employer, unfortunately. If you can't navigate to census.gov in a web browser, you probably won't be able to use tigris.

I think so too I'm accessing outside US. Thank you for feedback
