safari can't establish a secure connection

I changed service providers and was trying to change email addresses and passwords. I must have deleted something I shouldn't have, because now on safari I cannot get on icloud on the web and cannot sign into support communities on safari. I have no trouble with other browsers just safari. I get a message saying "safari can't establish a secure connection to the server idmsa.apple.com. what do i need to get back on

iMac, macOS Sierra (10.12.6)

Try setting up another admin user account to see if the same problem continues. Also try the Safe Mode.

also Sierra


Safe Mode Startup – El Capitan. also Sierra


If it works in the Safe Mode, try running this program when booted normally and then copy and paste the output in a reply. The program was created by Etresoft, a frequent contributor.
