I am using macOS 10.13.6. When I go to www.twitter.com in Google Chrome I get a
This site can't be reached. https://www.twitter.com/ is unreachable. ERR_ADDRESS_UNREACHABLE
On the same machine I can fire up Safari and I can get to the same url with no problem. On Chrome I tried using a guest and incognito account with no luck. I also used the settings feature to restore settings to their original default. Nothing seems to help. I am not having this problem with any other site, just twitter.
