I have the same problem on 16 pro max , even tried to reset and reload from backup. Still the same error .I don’t know what to do…

I have the same problem ( unable to check for updates-an error occurred)I tried to do everything what is possible to fix it but nothing change . Also I tried to reset all settings and reinstall from backup but it comes back again. To be honest I think this is some kind of connection error. Anyone knows how to fix it???
