Google lens through smoothwall

[Sheridan]

We're trying to get google lens/camera search to work with iOS devices - connected to the wifi as a student account and passed to the smoothwall with the same student credentials

 

The search part of the google app simply says 'can't reach the internet' when you try to search open the camera to search, or open the translate option

 

Does anyone have a list of what needs to be allowed to get this working, as we don't allow Gmail etc for students I don't want to just start unblocking all sorts of subdomains!
