Sometimes the internet access in the Android simulator does not work if connected to an iPhone Hotspot. Chrome won't load any page, apps cannot connect to servers. This can be fixed by added a public DNS under the Network settings in System Preference in macOS for the hotspot. Choose the Hotspot connection > Advanced > DNS and under the DNS Servers: add 8.8.8.8 and 8.8.4.4. Then relaunch the emulator to get internet access.
