In your SDK, you have a VAConsumer application which I have built and run : I do not get same results as your test tool with my credentials.
Therefore, I ask the following:
1) Source code to SampleContributionsChannelPublisher if you can get it; If not, then
2) Configuration for VAConsumer that allows our credentials below (from attached .INI file) to work and contribute to our RIC codes:
Do we need a company specific SSL cert? We can connect to ads, to deliver quotes, but cannot do it 'right'.
Refer to this website, the RCC server uses the certificate issued by Comodo.
As I know, VAConsumer can connect to RCC but it is unable to contribute data to RCC. You can refer to the tutorials in the Refinitiv Real-Time SDK - C/C++.
Did you check the ETA Consumer - Posting data to Contribution Channel tutorial page yet? The tutorial provides a step-by-step guide to build and run the VAConsumer to contribute data to the RCC server. You can download the example code from RTSDK C++ Tutorial Source Code download page.
