Concurrent Connections from Same Device

I have a script setup on my local device that runs ml_walkforward against my cloud server. I want to run multiple simultaneous ml_walkforward runs against the server in parallel from my local device. However, when I try this I get the max concurrent installs is two error. Is this expected behavior? The docs don't clarify how many open connections and requests I can make from the second device. If not how do you suggest running multiple requests from the same remote device to run multiple backtests? Thanks!
