The exception message implies that the login stream currently is not opened. It seems that your login request with different IP address has been rejected so the stream was closed.
Please verify the Login response received in your application. For the "RFA .Net Tutorials / step 8", the Login response will be logged to console. Below is the example of the Login Denied response.
<- Received MMT_LOGIN - Login DeniedstreamState : CloseddataState : SuspectstatusCode : NotAuthorizedstatusText : A21: A required argument was NULL
You can post the Login response and the value passed in the POSITION field here.
Please provide details of error message you encounter and also include code snippets and any config files that you are using.
Invalid usage exception message:“OMMConsumer::registerClient() has been called with anitem request prior to login request. Login request is expected first.”
When I pass an IP address different from the default value "127.0.0.1/net", the login request passes but an exception is raised when sending a subscription request. This error message sounds like the login request was not sent or taken into account. I am using the sample code provided in "RFA .Net Tutorials / step 8", with RFA API .Net version 7.5.0.L1.
