Can't connect to iCloud using Safari
when I try to connect to icloud.com, before I get to the username & password, I get the message "Connection Error
iCloud encountered an error while trying to connect to the server"
I get black line across the top of the screen and some apple links across the bottom, so I'm partway in... but never get to the verification screens.
Firefox works fine (that's what I'm using now)
When I tried to log into the help section to make a posting, it tells me that Safari can't open the page because...... it can't establish a secure connection to the server idmsa.apple.com. (once again Firefox is fine).
I'm baffled.
Ideas?
Using Safari 13.0.5; OS 10.13.6
