I have been running a tezos node for a while. I have a script that checks the blockchain state using this node regularly. Newer versions of the node seem to allow fewer requests. I regularly get timed out or I get a "Too many requests (429)" error.
How do I raise this limit? I am not overloading the server, I can't even do two orders of magnitude less requests than I used to be able to and the PC the node is running on is idle.
