    Hi @luxiangyuan

    Please see this existing thread discussing the same warning message.

    Looking at the limited log extract that you provided, it looks like the server disconnected your application. Possible causes for such a disconnection are component restart, bandwidth exhaustion, or network
    outage.

    Is this happening frequently or was this a one of incidence? Did the connection eventually re-establish itself?

    If it is happening more than once, did it start to happen after your changed your RequestTimeOut? If you are having ongoing connectivity issues, I recommend you contact Premium Support so they have help you diagnose your issue offline.

    hello Umer：

    I am glad to see your answer, thank you very much.

    1 I do not have the permission of the link "this existing thread"

    2 this happening frequently, and can not re-establish itself all the time; because If one RIC was lost ,I can not get any Msg of this RIC;

    3 It starts to happen after I add RequestTimeOut in the EmaConfig.xml,

    before I add the timeout option, I alaways get timeout errors.

    4 I do not have the permission of the link "this existing thread"

    Hi @luxiangyuan

    It seems that you may have replaced a timeout issue with a disconnect issue. This suggests a deeper problem with your application or connection. My suspicion would be that your connection /application cannot handle the volume of data you are receiving.

    Therefore, I recommend you create a support ticket via https://developers.thomsonreuters.com/group-support-form/1591/6011 - so that they can assist you in deeper diagnostic of the issue.

    If you cannot access the Support ticket form - please contact your Refinitiv account manager to arrange access.

    hello umer

    yes, I get timeout issue at the beginning,

    I ask a question on this web, someone suggest to add RequestTimeOut.

    After I add RequestTimeOut, I get "lost" issue.

    so generally speaking,

    Does RequestTimeOut is advocated to use?

    Hi @luxiangyuan

    There may be scenarios where adjusting the Timeout may help - but as explained in the post that was linked to your other RequestTimeOut question, the server / connection side does need to be investigated if adjusting the parameter does not resolve the issue.

    hello Umer

    thanks for your answer.

    I get either "Timeout" or "Service lost" when I connect my progrem with TREP through "public network";

    When I connect my progrem to TREP through "dedicated line", the errors disappeared, even I delete the equestTimeout.

    It seems that the errors were caused by "network"

    Ok - so per earlier suggestions, it sounds like your 'public' connection cannot handle the volume of data i.e. bandwidth?
