EMA: cannot authenticate towards RTO

Please check my colleague @Jirapongse answer about the EnableSessionManagement parameter setting.

All comments

I am not the EMA C++ expert, but there are 2 points that might help you.

First: Set the DeliveryDirect Authentication and Service Discovery URLs

I see that you are trying to connect to RTO via a DeliveryDirect network. Did you run the Cons113 with the following parmaters?

-tokenURLV2: specify the RDP Authentication URL for the DeliveryDirect
-serviceDiscoveryURL: specify the RDP Service Discovery URL for the DeliveryDirect

If you did not specify those parameters, the EMA uses a default RDP public connection endpoint (https://api.refiniti.com/xxxx).

Second: EncryptedProtocolType

The default configuration of the EmaConfig.xml should work fine without any modification on the EncryptedProtocolType paramter. Did you install the OpenSSL on that machine yet?

This How to Build OpenSSL, zlib, and cURL libraries on Windows article might help you.

I checked the attachment file.

The error message "Initialization timed out." on C++ and "login failed (timed out after waiting for 45000 milliseconds) for <endpoint>." on Java API mean the API success to authenticate with RDP, but fail to connect to the RTO endpoint.

Based on the given Java capture screen, the steps are as follows:

The API got authentication from the RDP Authentication service (us-east-1-api.refinitiv.biz/auth/oauth2/v2/token)
The API got endpoints list from the RDP Service Discovery
However, the API cannot establish a connection with the RTO endpoint (us-east1-xxxx-api.refinitiv.biz) on port 14002 on time (45000 milliseconds)

You can try to set the LoginRequestTimeout parameter on the EmaConfig.xml file to increase the waiting time to establish a connection with the RTO RSSL server.

If it does not help, I strongly suggest you contact the RTO Support team to verify why an application cannot establish a connection to that us-east-1-aws-2-med.optimized-pricing-api.refinitiv.biz endpoint via DeliveryDirect. You can contact the team via the https://myaccount.lseg.com/en/productsupport website.

Thanks for the clarifiaction @wasin.w,

it was actually expected that the final connection with RTO would fail, I just wanted to check that the login to RDP at least worked, but I could not be sure of the outcome.

To connect to RTO, you need to set the EnableSessionManagement to 1 in the Channel.

Please check my colleague @Jirapongse answer about the EnableSessionManagement parameter setting.

Thanks,

I'll add the setting and make a new run.

Hello,

I've done a new test using EnableSessionManagement set to 1, however from the output I didn't spot any particular difference. As double confirmation, and considering that for networking reasons it's expected that the API cannot establish a connection with the RTO endpoint, can I conclude that the output in attachment shows a successful authentication step to the RDP service anyway?

For EMA C++, you can enable REST log to verify the authenticaion process by using the following configurations (RestEnableLog and RestVerboseMode) in the Consumer setting.

        <Consumer>
            <Name value="Consumer_4"/>
            <ChannelSet value="Channel_4"/>
            <Logger value="Logger_1"/>
            <Dictionary value="Dictionary_1"/>
            <XmlTraceToStdout value="0"/>
            <RestEnableLog value="1"/>
            <RestVerboseMode value="1"/>
        </Consumer>
