Master-Slave error: the database system is starting up

From

Hello, 

I was advised to write a letter to you

Windows Server 2012 
Postgres 9.6 
I made a replication with the master server. On the slave server service 
postgres is running, but in log files slave's server "FATAL:  the database 
system is starting up" message will continue. 

when I try from the command line run the command 

psql.exe -U postgres` 
writes the following error: 

psql: ... Connection refused (0x0000274D/10061) ... 
My postgresql.conf configuration is on the slave server: 

listen_addresses = 'ip slave adress' 
hot_standby = on 
wal_receiver_status_interval = 0 
hot_standby_feedback = on 
My recovery.conf configuration is on the slave server: 

standby_mode = 'on' 
primary_conninfo = 'host=ip master server port=5432 user=postgres' 
primary_slot_name = 'slot_1' 
trigger_file = 'D:\Postgres Data\Start_master' 
Could you please to fix this issue? I don't understand what could be the 
problem. I've made shutdown the server, the problem is not resolved.

Thenk you very much

please execute "select * from pg_stat_replication;" and "select * from 
pg_replication_slots ;" on the master and show us the output.
Please check also the logs on the standby.

Did you set hot_standby=on on the slave as well.

Hello

on slave hot_standby is on

hot_standby = on            # "on" allows queries during recovery
