Concurrent connections time out above 20 connections

We have a fairly sized web-app, I can see railway allows up to 10,000 concurrent connections at a time but in load testing I cant even get over 20 connections without it severely impacting the app. I have upgraded to the pro plan just for sanity sake but I still get the same result. Here is the query I am running and the results. Railway:

loadtest -c 30 https://railway-dev.webiste-name.com -t 20 -k

loadtest -c 30 https://railway-dev.webiste-name.com -t 20 -k

Railway struggles at 150 Concurrent connections and only completes 296 requests in 20 seconds and this is just on the homepage which is releteviely light
