Hello,
Me and my team are trying to connect to the Realtime-optimzed instance via c# (asp.net core 8) code and we managed to do so but only on the windows11 machine from my colleague, on my macos 14.2.1 macbook pro m1 I'm always getting an error (see below).
Does this package use some specific feature which doesn't exist on macos ? We couldn't find anything about compatibility issues.
Enabling more trace logs via the config file also doesn't give more logs.
Did anyone had similar issues or maybe has some suggestion ?
Code
https://developers.lseg.com/en/api-catalog/refinitiv-real-time-opnsrc/refinitiv-real-time-csharp-sdk/tutorials#ema-consumer-connecting-to-real-time-optimized It is the same code as in this tutorial just wrapped in a function which is getting called via an endpoint in asp.net core.
