Resubscribing after advice:"reconnect:handshake"

[Wangofandango]

Hey! I have a problem in a specific situation where i the server i am connecting to (that i dont have control over) sometimes shut off (or just restart). When we lose the connection, we get this error on the longpolling:

{"id":"13641","channel":"/meta/connect","successful":false,"error":"401:lfzlt13a0h2j53oqb9b5mpwhxnn0nov:Unknown client","advice":{"reconnect":"handshake"}}"

And as i see it currently, the handshake is successfully done. But since we are not also "re-" subscribing, then we dont any longer get any messages.

So if someone could please help me get an overview of how i can setup an automatic "Re-Subscribe" feature for when this happens 😓 I have sat with this problem for a very long time now

If it is any help, this is the code i am using when starting my client:

` public RelatelHostedService(IMessageListener messageListener, ILoggerService loggerService)
{
_messageListener = messageListener;
_loggerService = loggerService;

}

public Task StartAsync(CancellationToken cancellationToken)
{
    StartRelatelConnection();
    return Task.CompletedTask;
}

public Task StopAsync(CancellationToken cancellationToken)
{
    RelatelChannel.Unsubscribe();
    RelatelBayeuxClient.Disconnect();
    
    return Task.CompletedTask;
}

private void StartRelatelConnection()
    {
        string relatelServer = Config.RelatelServerEndpoint;
        string companyId = Config.KeyholesCompanyIdAtRelatel;
        string accessToken = Config.RelatelAccessToken;
        
        
        //"Options" for the longpolling transport (such as timout, interval, etc)
        Dictionary<string, object> options = new Dictionary<string, object>();
        
        
        //Optional HTTP headers to be sent with the longpollingtransport
        NameValueCollection httpHeaders = new NameValueCollection();
        
        LongPollingTransport clientTransport = new LongPollingTransport(options, httpHeaders);
        RelatelBayeuxClient = new BayeuxClient(relatelServer, clientTransport);
       
        //Adds access_token to outgoing meta messages, (so far only used on Subscribing)
        RelatelBayeuxClient.AddExtension(new AuthTokenExtension(accessToken, _loggerService));
        
        RelatelBayeuxClient.Handshake();
        RelatelBayeuxClient.WaitFor(10000, new List<BayeuxClient.State> { BayeuxClient.State.CONNECTED });
    }

}`
