Zoom no longer works - did something change?

[Vladhed1]

On Sept 2, 2025 I tried to join a Zoom meeting while out, and it failed to connect.  On fact the whole zoom app seems to not work anymore, except if I join the meeting while on WiFI, then go out?!

All other apps still work: Teams, Google Meet etc...

One clue, as I try to join, my LTE icon gets this leaf/oval symbol over it.  Anyone know what that means?  Google Speed Test still clocks in at 30Mbps.   Samsung A15 LTE version.

Worked around this for a while by forcing 3G UTMS but now it works properly with LTE.  Not sure what changed.  Don't get the funny leaf symbol over the LTE symbol anymore.  Zoom app updated in November so maybe that was it.

Thanks @hTideGnow, relieved to know it's not public blocking ports or something.

I tried all those things.  Next step is to reset the phone and only install zoom to see if it's something else blocking it.

It's weird that I can start a meeting on WiFI and have it keep working as I drive away, using LTE,

HI @Vladhed1 

I just tried to start a Zoom meeting and it works

Try to uninstall and reinstall Zoom

Also, make sure Zoom is not blocked from using mobile data
To enable the Zoom app to use mobile data, ensure mobile data is active for the app in your phone's settings (Settings > Cellular/Data > Zoom) and check that the app is up-to-date. If it's still not working, restart your device, clear the Zoom app's cache, or uninstall and reinstall the app
