    Hello @gang.chen1

    I have checked the log.txt and found a lot of Dictionary request timeout messages

    警告: loggerMsg

    Can the client replicate the issue with EMA Java example 450 (example450__MarketPrice__QueryServiceDiscovery or ex450_MP_QueryServiceDiscovery - if using RTSDK 2.0.0L1)? If so, which "-location" value that the client specify?

    Hi Wasin,

    Customer is using Elektron-SDK-1.5.0.L1.java with example450__MarketPrice__QueryServiceDiscovery. I will let customer try to use RTSDK 2.0.0L1 version to see if the issue still exists.

    Thanks
