Error adding Gmail to Mac

I changed my password on my gmail account using my iphone. When I turned on my iMac it wouldn't let me change the password. Errror message : Connection Insecure - Failed to verify the server certificate. This could be because of your network configuration or your proxy settings.

I deleted my mail account from the @accounts. When trying to add it back it gave me the same message. When I tried to add it back using "Add Other Account" it didn't give me that message it gave me this: Unable to verify account name or password.

I have 2 other gmail accounts in the mail app working fine...it is an access problem between the iMac and Google. What protocols need to be changed. I am running Mac OS High Sierra 10.13.6
