Having trouble linking a file in email

Having trouble linking a file in email

I believe I have gone through the correct steps to link a png file within my email. The link is there in the test email, but when I go to open it I get an error message that says that page can't be reached. 

The url the link sends me to is:  https://sitesapi/files/images/643290253/hot_contacts.jpg?utm_source=ZohoCampaigns&utm_campaign=2T-9%20PDF%20Downloads%20with%20links_2017-06-22&utm_medium=email
