You can try to specify false for the useHttpClientHandler parameter when registering AddGoogleApiClients().

Otherwise, I am not sure what you can do. I don't work with frontends, sorry

Many thanks for your quick response.
I will try on this and take further investigating on the source code library.

@Nguyenthanhtoa How did you fix this?

[Nguyenthanhtoa]

Hi @PontusHolmberg,
I used the REST api to fetch the places data instead of library.
Reference: https://developers.google.com/maps/documentation/places/web-service/autocomplete
Feel free to ping me if you have any trouble when intergrating the REST api, I can share the sample code in .NET MAUI.

Oh, okey.
I actually solved the issue it self. Turns out that SetProxy is not supported on iOS by Maui even in .net8.
So i changed the HttpClientFactory and removed the Proxy argument when creating a new HttpClientHandler.

[Nguyenthanhtoa]

Yes, sure. Great to hear that!

Can you explain a little more ? I am facing the same issue in maui but in GoogleMaps.Geocode.LocationGeocode and i never created a HttpClientHandler. Thanks.

@remi-appsolu I downloaded/cloned the github project and added it to my VS project, so I could modify the library.
Then inside HttpClientFactory you will find the function GetDefaultHttpClientHandler.
In there, I just changed

var httpClientHandler = new HttpClientHandler
        {
            Proxy = webProxy
        };

To
var httpClientHandler = new HttpClientHandler();

That way it will never call SetProxy.

Hi @remi-appsolu ,

As you can see in my issue description, the GoogleApi works properly on Android, but not on iOS. So, my workaround on iOS is using HttpClient to send an request to https://maps.googleapis.com/maps/api/place/autocomplete/json and get the places result like this:
using (var client = new HttpClient())
{
var path = "https://maps.googleapis.com/maps/api/place/autocomplete/json?input=SEARCH_STRING&key=YOUR_API_KEY&types=(cities)&components=country:YOUR_COUNTRY_CODE";

HttpResponseMessage response = await client.GetAsync(path);

if (response.IsSuccessStatusCode)
{
    var json = await response.Content.ReadAsStringAsync();
    var predictionResponse = JsonConvert.DeserializeObject<PlacePredictionResponse>(json);
    return predictionResponse.Predictions
        .Select(p => new CityOfResidence { Name = p.Description, PlaceId = p.PlaceId })
        .OrderBy(c => c.Name).Take(10).ToList();
}

}
Do not forget to add Newton.Json & handle exception
