response status code 415 (Unsupported Media Type), while using client.Track()

[tartulab]

hello, I want to use client.Track() but I get error: System.Net.Http.HttpRequestException: 'Response status code does not indicate success: 415 (Unsupported Media Type).'

            Uri fullNodeServer = new Uri("http://**********");
            ExplorerClient client = new ExplorerClient(network, fullNodeServer);
            client.Track(userDerivationScheme);

other stuff, like client.GetFeeRat is working.

That's strange, what is the url? Is it a local network ip? or it goes through internet?
Did you tried update package/nbx?

[tartulab]

local network ip. its machine in the same network. I have cloned latest repo, like cupule days ago. for client library I'm also using latest nuget package (3.0.21). Ps I forgot to mention that in postman everything is working and I can track specific derivation scheme using post /v1/cryptos/btc/derivations/****

[NicolasDorier]

damn that's weird. Tests are using exactly the same client... will try to replicate

[NicolasDorier]

This seems to work...

var client = new NBXplorer.ExplorerClient(new NBXplorer.NBXplorerNetworkProvider(ChainName.Regtest).GetBTC());
var facto = new NBXplorer.DerivationStrategy.DerivationStrategyFactory(client.Network.NBitcoinNetwork);
var derivationScheme = facto.CreateDirectDerivationStrategy(new ExtKey().Neuter());
client.Track(derivationScheme);

Can you send me a project where you can repro?
