How to test the connection between postgresql, Matrix synapse and Nginx Server on Centos8 - postgresql

Question

I getting problem with the connecting nginx server, postgresql and Matrix Synapse
Postgresql
it is running see the systemctl status below .
-Synapse1 is the database and roshyara is user which I have already added in the postgresql .
hb_pga_conf files are as following
1 # TYPE DATABASE USER ADDRESS METHOD
2 local all all md5
3
4 # The same using local loopback TCP/IP connections.
5 #
6 # TYPE DATABASE USER ADDRESS METHOD
7 host all all 127.0.0.1/32 md5
8 host all all 0.0.0.0/0 md5
9 host all all ::1/128 md5
10 # IPv4 local connections:
11 host all all 127.0.0.1/32 md5
12 host all all 172.19.0.0/16 md5
Synapse homeserver.yaml file is as follwoing
1 # Configuration file for Synapse.
2 #
3 # This is a YAML file: see [1] for a quick introduction. Note in particular
4 # that *indentation is important*: all the elements of a list or dictionary
5 # should have the same indentation.

10 # each option, go to docs/usage/configuration/config_documentation.md or

However, nginx is showing the follwoing error . What can I do now and how can I test which connection is creating problem?

installed nginx
installed postgresql
installed matrix synapse
created homeserver.yaml
now the nginx server is showing upstream server is not available
