Hello,


I am trying to establish an RTO v2 connection using WebSocket with Java. I downloaded the class named "MarketPriceRdpGwClientCredAuth" from the following GitHub link: [https://github.com/Refinitiv/websocket-api/blob/master/Applications/Examples/RDP/java/MarketPriceRdpGwClientCredAuth.java](https://github.com/Refinitiv/websocket-api/blob/master/Applications/Examples/RDP/java/MarketPriceRdpGwClientCredAuth.java), and I attempted to run it with the parameters below.

However, I am encountering the following error:

To verify whether I can connect successfully, I also tried to connect using the RTO v2 tool from Speed Guide, but I received the same error:

Could there be an issue with my license information, or am I doing something incorrectly?


Thanks.

    Hello Wasin,


    As you suggested, I captured the traffic using Fiddler. Based on this traffic, I received the output (file is added new 10.txt) from the following address ("https://api.refinitiv.com/auth/oauth2/v2/token"). Does this indicate that my license information is correct? Or is there something else I should check?

    Hello @SelcukYAPICI,

    Your account information is correct and the application can successfully get a valid token, as shown in your logs. It may be that the debugging proxy that you are using is blocking the websocket requests. At this time, I would suggest to initiate a direct connection without a proxy.

    Hi @Gurpreet,


    As you mentioned, I commented out the code that enabled the requests to pass through the proxy. The logs that appear in the console are as attached below. As far as I can see, there hasn't been any change. What do you recommend?

    Hi @wasin.w,


    I made some improvements, but they were not sufficient, as I am still encountering the following error. For some reason, I cannot progress beyond obtaining the token. On the Fiddler side, I can only see the process up to the point where the token is retrieved. Do you have any advice for this situation?
