Why won’t screen time let me open any of my accounts on my iMac.

I suddenly can’t open any of my accounts on my iMac. If I click on my Outlook account or try to do a search a box pops up saying Oops you can’t see pages on this website. It’s not on the approved list in screen time. Why is this popping up? I haven’t changed any settings. It started yesterday. How do I fix it so I can get into my accounts? The problem is only on my iMac. iPad and iPhone works fine.

Thank you
