ACK Scans from Zoom

My router is logging ACK scans from 170.114.52.3, which is allocated to Zoom. These scans are not part of a normal pre-meeting setup, as they occur at all hours, e.g., 00:52:29 & 04:27:32, when I'm dozing away, and also throughout the day. They always come in on port 443.

 

Could these scans be legit?
