One of my customer is facing following issue for requesting real time data with EMA 3.5.0.0 version. And customer is connecting to ERT in cloud. Could you please advice what caused this issue and how to avoid it ? Thanks.

Hello @gang.chen1

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

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
