Can't create a new client

[ZioZen]

Hi,
I'm trying to create an app that use this api, but when i try to create a new client the program crash and tell me "System.ArgumentNullException: 'Value cannot be null.
Parameter name: path1"

This is the code that I used:

            var settings = new FactorySettings
            {
                AppHash = "0f5b4xxxxxxxxxxxxxxxca4d4",
                AppId = 1xxxxxx8,
                ServerAddress = "149.154.167.40",
                ServerPublicKey = @"-----BEGIN RSA PUBLIC KEY-----
.
.
.
-----END PUBLIC KEY-----",
                ServerPort = 443,
                SessionTag = "session", // by defaut
                Properties = new ApplicationProperties
                {
                    AppVersion = "1.0.0", // You can leave as in the example
                    DeviceModel = "PC", // You can leave as in the example
                    LangCode = "en", // You can leave as in the example
                    LangPack = "tdesktop", // You can leave as in the example
                    SystemLangCode = "en", // You can leave as in the example
                    SystemVersion = "Win 10 Pro" // You can leave as in the example
                }
            };
            // Create the client
            var clientApi = await ClientFactory.BuildClientAsync(settings).ConfigureAwait(true);

I don't know from where this path1 came from, and how to fix it.

I have the exact same code and have no problems. Do you have any inner exceptions?

[ZioZen]

No, I don't have any inner exceprion.
I put the code inside a try-cath and this is the error that I have:

System.ArgumentNullException: Value cannot be null.

Is possible that the problem is the ServerPublicKey? I put the entire key, and it give me the error; I try with only the RSA PUBLIC KEY, and I have the same problem...

I know that part is very strict. I have it exactly like this:

                string rsaPublicKey = @"-----BEGIN RSA PUBLIC KEY-----
MIIBC****
ly****
aq***
EfD****
8j****
Slm****
-----END RSA PUBLIC KEY-----";
