Rest Integration "Not Ready" & "Timeout"

I have quite a few REST endpoints in my HA setup, it seems that when I hit a certain threshold of rest sensors, HA isn’t able to handle all of them and stops. I usually switch over to Node-Red and pull them in but I am wondering if there is something I can adjust in HA for it to have more resources or time? It also may be the way I have the endpoints setup, each sensor value has its own string and credentials even though its the same device on my network.
