500: internal error / [Errno 111] Connection refused

Hello! I installed adventurelog using Proxmox VE Helper-Scripts, no problems installing but when I try to log-in with the creds I get to this:

PUBLIC_SERVER_URL is correctly set to the IP i'm using just with port 3000

I check back-end service and got this:

systemctl status adventurelog-backend.service
