Self-hosted WCF can connect to localhost but can't connect remote
I have a self-hosted C# WCF .Net 4.6.1 Windows service that communicates with another self-hosted WCF service. This works fine when both services are on the same server. However, when I move the server to another computer, I get this error:
System.ServiceModel.CommunicationException: The socket connection was aborted. This could be caused by an error processing your message or a receive timeout being exceeded by the remote host, or an underlying network resource issue. There are no firewalls running on either computer and I get a response when using http://192.168.1.129:6253/eTutorWcfService (using net.tcp in app).

try

When the client tries to connect, the output window of the server shows an SecurityTokenValidationException but I'm not sure what to do about that or if it means something relevant. I'm sure this has something to do with security but I don't know what to add where.

Use sniffer like wireshark or fiddler and compare results on working PC and non working PC. Look at http response status to see if you are getting 200 done. Also check the TCP to see if you are getting [FIN] which terminates a TCP connection indicating finish.

Maybe your entry<identity> <servicePrincipalName value = ""/> </identity>in the client config has to do with theSecruityTokenValidationException. I don't know, why it is in the config.

On the identity, it gets added automatically at some point with "msi/steve" (host name/user). I've taken out the value and the node but get the same error.

First, Nettcpbinding use transport security mode and authenticate the client with windows credential by default.
WCF throws exception that the server has rejected the client credentials, what is the default security mode for NetTCP in WCF
Then, when we change the server configuration and re-host the service, we should re-generate the client proxy class when we calling it. besides, we may need to change the endpoint address in the client configuration since Localhost is generated by default.
I can live with this but would really like to know how to do it
without security.
At last, when we change the security to None, the client does not need to provide the credentials to invoke the service. I suggest you re-host the service and re-generate the client proxy class. I have made a demo, wish it is useful to you.

I added the following code and it works:
client.ClientCredentials.Windows.ClientCredential.UserName = runAs;
client.ClientCredentials.Windows.ClientCredential.Password = runAsPassword;
client.ClientCredentials.Windows.ClientCredential.Domain = runAsDomain;
However, I'd like to do this without security since it will be placed on multiple servers, none of which will have a public IP. I've tried to add to the bindings but on the client it's not a valid node and on the server, it stops the service from starting. I tried to add the following code to the server but it won't open the ServiceHost:
serviceHost.AddServiceEndpoint(typeof(eTutorWcfService), new NetTcpBinding(SecurityMode.None), "");
I can live with this but would really like to know how to do it without security.

First, Nettcpbinding use transport security mode and authenticate the client with windows credential by default.
WCF throws exception that the server has rejected the client credentials, what is the default security mode for NetTCP in WCF
Then, when we change the server configuration and re-host the service, we should re-generate the client proxy class when we calling it. besides, we may need to change the endpoint address in the client configuration since Localhost is generated by default.
I can live with this but would really like to know how to do it
without security.
At last, when we change the security to None, the client does not need to provide the credentials to invoke the service. I suggest you re-host the service and re-generate the client proxy class. I have made a demo, wish it is useful to you.

I added the following code and it works:
client.ClientCredentials.Windows.ClientCredential.UserName = runAs;
client.ClientCredentials.Windows.ClientCredential.Password = runAsPassword;
client.ClientCredentials.Windows.ClientCredential.Domain = runAsDomain;
However, I'd like to do this without security since it will be placed on multiple servers, none of which will have a public IP. I've tried to add to the bindings but on the client it's not a valid node and on the server, it stops the service from starting. I tried to add the following code to the server but it won't open the ServiceHost:
serviceHost.AddServiceEndpoint(typeof(eTutorWcfService), new NetTcpBinding(SecurityMode.None), "");
I can live with this but would really like to know how to do it without security.

Local host may be configured different on two PCs. Check host files : C:WindowsSystem32Driversetchosts

No entries in the hosts file on either computer.

Use sniffer like wireshark or fiddler and compare results on working PC and non working PC. Look at http response status to see if you are getting 200 done. Also check the TCP to see if you are getting [FIN] which terminates a TCP connection indicating finish.

Maybe your entry
<identity> <servicePrincipalName value = ""/> </identity>in the client config has to do with theSecruityTokenValidationException. I don't know, why it is in the config.– H.G. Sandhagen
Jan 1 at 15:57
On the identity, it gets added automatically at some point with "msi/steve" (host name/user). I've taken out the value and the node but get the same error.
