Failing to authenticate when used against MIT Kerberos Server

Start by reproducing the Docker Compose MIT Kerberos setup and compare it with the successful kinit result. Trace the timeout from Kerberos.NET/Transport/Tcp.cs line 57 through Client/Transport/TcpKerberosTransport.cs line 129 and KerberosClient.RequestTgt; done means the provided C# authentication call obtains a TGT successfully.

Describe the bug
The library seems to be failing when trying to talk to MIT Kerberos Server. I've setup a test MIT Kerberos Server, create a principal and trying to use Kerberos.NET to try to obtain TGT. This is failing with

System.Threading.Tasks.TaskCanceledException: A task was canceled.

I am able to authenticate with kinit without issues

To Reproduce

1. Create a docker-compose file like this

version: '3.0'
services:
  demo:
    image: gcavalcante8808/krb5-server
    ports:
      - '88:88'
      - '749:749'
      - '464:464'
      - '888:888'
    environment:
      KRB5_REALM: MACSUX.DC
      KRB5_KDC: localhost
      KRB5_PASS: password

2. Launch the server from shell via docker-compose up command
3. Add user to the kerberos server by executing the following command (adjust container name if necessary)
   docker exec krb-test-server-demo-1 /bin/sh -c "echo password | kadmin -r MACSUX.DC -p admin/admin@MACSUX.DC -q 'addprinc -pw password iwasvc@MACSUX.DC'"
4. Try to authenticate to this server via a program like this:

var realm = "MACSUX.DC";
var config = Krb5Config.Default();
config.Realms[realm].Kdc.Add("localhost");
config.Realms[realm].DefaultDomain = realm.ToLower();
config.DomainRealm.Add(realm.ToLower(), realm.ToUpper());
config.DomainRealm.Add($".{realm.ToLower()}", realm.ToUpper());
var client = new KerberosClient(config);
var credentials = new Kerberos.NET.Credentials.KerberosPasswordCredential("iwasvc", "password", "macsux.dc");
await client.Authenticate(credentials);

Expected behavior
Authentication successful

Screenshots

Additional context
Tested on Windows with server running in docker. kinit test was performed from WSL and was successful.
