# Vault 2 issues with Nginx Proxy not working

Check logs in Portainer - bind port already used (80)

```bash
 lsof -i tcp:80
```

This will show whats running on that port

```bash
fuser -k 80/tcp
```

This should kill the process, but if not do the below (based on the COMMAND Name)

```bash
systemctl stop haproxy
```
