host - Windows Server 2022
postgresql - 14.8
pgAdmin 4 - 7.1
openssl - 3.1.0
So I have generated a key and csr file to be sent to a CA cert issuer
InCommon. I generated via openssl with the following command.
openssl.exe req -newkey rsa:2048 -nodes -keyout postgresql.key -out postgresql.csr
Downloaded the
PKCS#7, PEM encoded version of the cert to use. The following is the changes I did to postgresql.conf. The x.x.x.x is the actual IP of the Server.
listen_addresses = 'x.x.x.x'
ssl = on
#ssl_ca_file = ''
ssl_cert_file = './certs/postgresql.cer'
#ssl_crl_file = ''
#ssl_crl_dir = ''
ssl_key_file = './certs/postgresql.key'
#ssl_ciphers = 'HIGH:MEDIUM:+3DES:!aNULL' # allowed SSL ciphers
#ssl_prefer_server_ciphers = on
#ssl_ecdh_curve = 'prime256v1'
#ssl_min_protocol_version = 'TLSv1.2'
#ssl_max_protocol_version = ''
#ssl_dh_params_file = ''
#ssl_passphrase_command = ''
#ssl_passphrase_command_supports_reload = off
Here is the current setup of pg_hba.conf with real IP's being x.x.x.x
# "local" is for Unix domain socket connections only
#local all all scram-sha-256
# IPv4 local connections:
#host all all 127.0.0.1/32 scram-sha-256
#host all all x.x.x.x/32 scram-sha-256
host all all x.x.x.x/32 scram-sha-256
hostssl all all 127.0.0.1/32 scram-sha-256
hostssl all all x.x.x.x/32 scram-sha-256
hostssl all all x.x.x.x/32 scram-sha-256
# IPv6 local connections:
# host all all ::1/128 scram-sha-256
# Allow replication connections from localhost, by a user with the
# replication privilege.
local replication all scram-sha-256
host replication all 127.0.0.1/32 scram-sha-256
# host replication all ::1/128 scram-sha-256
The problem I am running into is my remote client can't connect via SSL to
postgrsql. I am able to from the server itself. This is using pgAdmin 4 and making ssl mode as required. Also ran psql.exe on the server to show that SSL was in fact working on the server. "SSL connection (protocol: TLSv1.3, cipher: TLS_AES_256_GCM_SHA384,
bits: 256, compression: off)". In the logs it is showing this when I try to connect via my remote client.
[2672] LOG: could not accept SSL connection: An existing connection
was forcibly closed by the remote host.
The error from pgAdmin 4 on the remote client is this.
connection failed: server closed the connection unexpectedly
This probably means the server terminated abnormally before or while processing the request. SSL SYSCALL error: Connection reset by peer (0x00002746/100054)
I have been trying to find a solution with no luck. I am hoping
that I might be missing something simple and someone will be able to see it.
