Gtting 401 error with client generated Kerbeors token added to .net 7 httpclient

**Describe the bug**
cannot get token to authenticate

**To Reproduce**
.net 7 app Using httpclient with UserDeaultCredentials set to falue

var client = ClientFactory.CreateClient("SuperAssociate");
HttpContent inputContent = new StringContent(GetEvent(), System.Text.Encoding.UTF8, "application/json");

DnsQuery.RegisterImplementation(new PlatformIndependentDnsClient());

var kClient = new KerberosClient();
var kerbCred = new KerberosPasswordCredential("XXXXXX", "YYYYYYY", "salelytics.local");

await kClient.Authenticate(kerbCred);

var ticket = await kClient.GetServiceTicket("host/webtest01.salelytics.local");

var apiHost = "http://webtest01.salelytics.local/";
Guard.Against.NullOrEmpty(apiHost);

client.BaseAddress = new Uri(apiHost);
var apiSite = "SuperAssociateRuss/api/IncomingEvent/";

client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Negotiate", Convert.ToBase64String(ticket.EncodeGssApi().ToArray()));

var apiResponse = await client.PostAsync(apiSite, inputContent);

**Expected behavior**
The Authorization Header should validate as my user

The token I get from Kerbeoros.Net is different from the one my chrome browser is sending. should it be the same?
