> After upgrading from 2.4.2 to 2.6.x discourse is no longer working for us. The issue is discourse is trying to connect to port 3000 on 127.0.0.1. I have rebuilt web\_only numerous times with ./launcher rebuild web\_only Questions. What is supposed to be running on 127.0.0.1:3000? How to restart that service? Cheers and thanks!
