Firebase Dynamic Links Service: The remote name could not be resolved: 'firebasedynamiclinks-ipv6.googleapis.com'

Hi, I was using Firebase Dynamic Links API, but I encountered an issue.

Code:

var firebaseDynamicLinksService = new FirebaseDynamicLinksService(
    new BaseClientService.Initializer { ApiKey = ApiKey });

var LongDynamicLink = FDL_URL + "/?link=" + link;
var createShortDynamicLinkRequest = new CreateShortDynamicLinkRequest() { LongDynamicLink = LongDynamicLink, Suffix = new Suffix() { Option = "SHORT" } };

var request = firebaseDynamicLinksService.ShortLinks.Create(createShortDynamicLinkRequest);
var response = request.Execute(); // Throw exception

Exception:

{System.Net.WebException: The remote name could not be resolved: 'firebasedynamiclinks-ipv6.googleapis.com'
   at System.Net.HttpWebRequest.EndGetRequestStream(IAsyncResult asyncResult, TransportContext& context)
   at System.Net.Http.HttpClientHandler.GetRequestStreamCallback(IAsyncResult ar)}

But I can successfully post and generate a shortened link manually by:

var json = "{\"longDynamicLink\":\"" + FDL_URL + "/?link=https://youtube.com\",\"suffix\":{\"option\":\"SHORT\"}}";
var response = await firebaseDynamicLinksService.HttpClient.PostAsync("https://firebasedynamiclinks.googleapis.com/v1/shortLinks?key=" + ApiKey, new StringContent(json, Encoding.UTF8, "application/json"));

When I change the requestUri to “https://firebasedynamiclinks-ipv6.googleapis.com/”, I get the same error.

var response = await firebaseDynamicLinksService.HttpClient.PostAsync("https://firebasedynamiclinks-ipv6.googleapis.com/v1/shortLinks?key=" + ApiKey, new StringContent(json, Encoding.UTF8, "application/json"));

@yurik94, @jackson777 Thanks for showing a workaround. This has now been internally acknowledged as a configuration error. The correct hostname should be (as you guessed) firebasedynamiclinks.googleapis.com. Hopefully it’ll be fixed soon.

This is fixed in the latest nuget release: https://www.nuget.org/packages/Google.Apis.FirebaseDynamicLinks.v1/1.33.0.1210 The correct hostname can be seen in firebasedynamiclinks_v1.json and Google.Apis.FirebaseDynamicLinks.v1.cs.
