Dear I have 2 Sierra Chart installed on 2 different computers (Computer A, SC version 2280 and Computer B, SC version 2291). Both computer has the same configuration, data service is Interactive Brokers. The data feed works fine when there is ONLY ONE SC runs on either Computer. However, when I have 2 SC runs on BOTH Computer A AND B, only ONE computer can successfully connect to the server and receive real data. The other computer unable to login to the server but keep retrying and receiving below message. SC Data - All Services | Connecting to the server ds1.sierracharts.com. Port 443 | 2021-08-12 20:52:55.193 DTC Client socket (1) | Creating socket. | 2021-08-12 20:52:55.194 DTC Client socket (1) | New receive buffer size: 5242880 | 2021-08-12 20:52:55.194 DTC Client socket (1) | Connecting to IP: 8.18.161.135. | 2021-08-12 20:52:55.194 SC Data - All Services | Network connection to server complete. | 2021-08-12 20:52:55.466 SC Data - All Services | Starting socket receive thread. | 2021-08-12 20:52:55.466 SC Data - All Services | Sending encoding request to server: Binary VLS.

I used to be able to get real data for BOTH Computer A and B might be 2 months ago with previous versions .... Thanks for your help. |
