Hi, I received HTTP error 500 for following connect request (EMA, C++, Real-Time-SDK-2.0.1.G1 ). Any idea what could this be ? Note that i did not exceprience this issue in a different env (another redhat8) with same client application. I could've assumed this to be related with some env configs, but 113_MP_SessionMgmt example was executed successfully in the same environment in which following issue was noticed.

    Hello @thilinaillangasinghe

    Firstly, you are using the RTSDK version 2.0.1.G1 which is the development release and is not recommended to run on the production environment. The information on the release types is as follows:

    • "L" releases (e.g., 1.2.0.L1) are full RTSDK releases that have been fully tested and recommended for the production
    • "E" releases (E-Loads) are emergency RTSDK releases for fixing specific issues
    • "G" releases (e.g., 1.2.0.G1) are releases that are the development release.

    I highly recommend you re-test the issue with the latest SDK version 2.0.5 L1. You can download the SDK from the following links:

    The error message indicates that the API got HTTP error 500 from the RDP Authentication service while it tried to send the authentication request to RDP. Can you test a connection from that machine to RDP Auth Service with the following command?

    curl --location --request POST 'https://api.refinitiv.com/auth/oauth2/v1/token'; \
    --header 'Content-Type: application/x-www-form-urlencoded' \
    --header 'Authorization: Bearer ' \
    --data-urlencode 'username=<Machine ID>' \
    --data-urlencode 'password=<Password>' \
    --data-urlencode 'grant_type=password' \
    --data-urlencode 'scope=trapi' \
    --data-urlencode 'takeExclusiveSignOnControl=true' \
    --data-urlencode 'client_id=<App Key>'


    If you can replicate the issue on demand, please enable the REST log messages and share the error messages (please remove your credentials) in this post. You can set the REST log with the following parameters on the EmaConfig.xml file.

    Additionally, are you using the same RTO Machine-ID with multiple applications/sessions?
