OT: My iCloud mail won't work

[Das Goravani]

Dear All,

My iCloud mail account has a circle with a squiggly line through it on my Mac. It is the symbol of no connection. It is not working. 

Any ideas on how to get it working?

I’m on a MacBook Pro using Sonoma as my OS. 

Clicking on the circle does nothing.. nothing happens. 

I have taken the account online a number of times but nothing happens. 

Does Apple cancel iCloud membership at some point as your Mac ages? 

Thanks for any help,
