Just use HttpClient to make a call to the endpoint and see if you get a response or a timeout before trying to load the map.  This uses the generic sharing Url, but could use the Url of the basemap itself public override async Task<bool> CheckIsConnectedAsync() { try { var tokenUri = new Uri($"{ConnectionUrl}/sharing/rest?f=json"); HttpClient client = new HttpClient { Timeout = TimeSpan.FromSeconds(7) }; var result = await client.GetStringAsync(tokenUri); var jsonObject = JsonConvert.DeserializeObject<Dictionary<string, object>>(result); return jsonObject.ContainsKey("currentVersion"); } catch ( TaskCanceledException ) { //timeout - server down return false; } catch ( Exception ) { //Can connect but server not fully up and running return false; } }   If you are using Xamarin the Essentials library has methods to check general device connectivity as a way to look at that. ...

Never found a way to get anything to work with the Runtime API, but was able to do using the rest endpoint directly.   string zipfileName = CreateProjectZipfile(projectItem); /* Does not seem that Runtime API handles creating a zip file item, so using rest API directly /* https://developers.arcgis.com/rest/users-groups-and-items/add-item.htm */ string url = $"https://www.arcgis.com/sharing/rest/content/users/{portal.User?.UserName}/additem"; using ( var formContent = new MultipartFormDataContent() ) { AddStringContent(formContent, projectItem); AddFileContent(formContent, zipfileName, projectItem); using ( HttpClient client = new HttpClient(new ArcGISHttpClientHandler()) ) { var response = await client.PostAsync(url, formContent); var json = await response.Content.ReadAsStringAsync(); await ShareItemWithGroupAsync(json); } } private void AddStringContent(MultipartFormDataContent formContent, ProjectItem projectItem) { Dictionary<string, string> parameters = new Dictionary<string, string>() { { "multipart", "false" }, { "title", projectItem.Title }, { "type", "Code Sample" }, { "async", "false" }, { "f", "json" } }; // For MultipartFormDataContent paramaters needs to be added as individual StringContent objects. FormUrlEncodedContent does not work. foreach (var keyValuePair in parameters) { formContent.Add(new StringContent(keyValuePair.Value), keyValuePair.Key); } } private void AddFileContent(MultipartFormDataContent formContent, string outputfile, ProjectItem projectItem) { var byteArrayContent = new ByteArrayContent(File.ReadAllBytes(outputfile)); byteArrayContent.Headers.ContentType = new MediaTypeHeaderValue("application/x-zip-compressed"); byteArrayContent.Headers.ContentDisposition = ContentDispositionHeaderValue.Parse("form-data"); byteArrayContent.Headers.ContentDisposition.FileName = $"{projectItem.Title}.zip"; // ContentDisposition.Name needs to match the parameter name byteArrayContent.Headers.ContentDisposition.Name = "file"; formContent.Add(byteArrayContent); }   ...
