Royal Caribbean No Longer Recognizes 1P

Trying to login to Royal Caribbean website (https://www.royalcaribbean.com) and 1P does not recognize it. This just started - never had this problem. Have to copy and past to login. Tried quitting 1P and Safari and even rebooting computer but nothing works.

So I deleted my login from 1P, thinking maybe the website changed something and I could just read it - but that doesn't work either - when I go to sign in, 1P will not ask me if I want to save the login in 1P and I can't figure out how to force it to do so. Same thing on Firefox browser - and same thing happens trying to login to my wife's Royal Caribbean account.

All other websites work correctly.

What is going on?
