Meetings cutting out

Hi, 

In the past few weeks, within the first 5 mins of most Zoom sessions I'm hosting, the connection cuts out (despite both my own and my clients' internet connection being totally fine). Initially it just glitches and the video freezes, and then connection is lost. I've taken to exiting the session and re-starting it, and am asked if I want to 'reclaim host', which I do. Then there are two of 'me' (as in, one with just my name and video off) in the space with my client for a few mins, until the other 'me' disappears. Has anyone else experienced this / has a solution? It's quite disruptive to sessions!
Thanks, 

Beth
