Uptime monitoring on a site with a redirect

HI,

My site is redirected to http://www.sanlambewell.co.za/sanlam (this effectively acts as the home page for that domain). Now when I try activate uptime monitoring I get the following message:

"It appears that your home_url setting is trying to redirect to another domain. This often happens when you are forcing https but haven't updated your site setting for that. Please verify that the home_url option of your WP install is correct, then click refresh updates in the Dashboard plugin."

So what is the correct way to get the domain added? Should I be adding each individual multisite to the dashboard separately?
