Error Code 5003 when logging on via cellular data but not when logging on via wifi

[Ann25]

Following a recent Zoom update approx 2 weeks ago, my iPad will log on to Zoom normally via wifi, but won't log on via 4G cellular data. It gives an error code 5003.  Prior to this it has worked normally.  I have uninstalled and reinstalled the app several times, but the error code persists when I attempt to log in via cellular data.  There is no firewall or proxy.  Thankyou for any suggestions as to how to solve this problem.

For what it's worth, I'm having the same problem on iPhone! Really annoying
