I have 2 nodes. One of them is PmmClient, other is PmmServer.  
I installed Postgresql on the PmmClient node and successfully sent the queries to PmmServer node. There was no any problem.  
After days,  
I installed Patroni on the PmmClient node and I am getting this error message When I try to add postgresql.

> sudo pmm-admin add postgresql --username=‘pmm’ --password=‘pmm’  
> `Connection check failed: dial tcp 127.0.0.1:5432: connect: connection refused.`

Here is the listening port

> sudo lsof -i -P -n | grep LISTEN

```auto
patroni 623929 postgres 5u IPv4 752493 0t0 TCP x.x.x.198:8008 (LISTEN)
postgres 624009 postgres 5u IPv4 753603 0t0 TCP x.x.x.198:5432 (LISTEN)

```

Here is the pmm-admin status output

```auto

Hi @HKN_MZ

Welcome to the Percona Forums. Thanks for being part of the community.

Could you try this?

```auto
sudo pmm-admin add postgresql --username='pmm' --password='pmm' --host=$(hostname) --port=5432

```

Thanks!

Pep
