Error: redis connection to 127.0.0.1:6379 failed - connect ECONNREFUSED 127.0.0.1:6327 Steam exchange bot, Nodejs error. Who worked with bots?

Question

Node.js

Hello people of Toaster. There is a problem with the steam inventory sharing bot. In general, we deployed a bot on a local server and it is cut down in 4-5 seconds after the load reaches 140%. The car is powerful, it's not about the car. It seems that somewhere in the code there is a very powerful cycle, and maybe more than one.
Deployed to windows

I'm attaching a screenshot of the mess.

Tell me what could be the problem. At least direct to the right steppe.
Thank you for your attention.
