You are most likely using the wrong port number with the client.
Format: #./client <server-address> <port-number>
If the server is running on the same machine then use server address as 127.0.0.1 and always use right port number( which you are making the mistake at)
If this still doesnt work, then make a sanity check if the server is running by
If it returns a valid integer then the server is running or else you need to.

GEMS-SERVER(1) gems documentation GEMS-SERVER(1)NAME
gems-server - Transmit a shell session in real time.
SYNOPSIS
gems-server [-ip ip] [-port p] [-maxconn n] [-wait m] [-log dest] [-noscript] [-script_bin script]
gems-server -h | -v
DESCRIPTION
Transmits a shell session to be shown in real time in various different computers or terminals.
gems-server transmits data in real time to clients via a network connection. Each one of these clients must run the gems-client(1) program
to establish connection and receive the transmitted data. Clients can connect and disconnect at any given time, but of course they will
only receive the data that is transmitted while they are connected (just like a radio transmission/reception system).
The gems system is normally used to transmit a console session and show it in various computers at the same time, but it is also possible
to transmit any other kind of data.
OPTIONS -ip IP address where connections will be accepted.
-port TCP port. Default: 6666.
-maxconn
Do not accept more than n simultaneous clients. Default: 25.
-wait Wait until m clients are connected before starting the transmission. This is useful to ensure that the first m clients will receive
all data transmitted. The default behavior is to start transmission immediately, without waiting for client connections.
-log By default, the server does not write log messages. This option configures the destination of logs. The dest argument can be `sys-
log' (to log through syslogd(8)), `stderr' (to log through standard error output), or it can be an arbitrary filename (log messages
will be appended to the file, if it exists).
-noscript
By default, the server executes the script(1) program to take terminal data and transmit it. When this option is used the server
will not run script, and data will be read form standard input.
-script_bin
Specifies the location of the script(1). program. Default: /usr/bin/script.
-h Show a short help message.
-v Show version information.
FILES
/var/lock/gems-server.PORT
Lock file. gems-server creates this file on initialization and deletes it on exit. PORT is replaced by the TCP port used. gems-
server will not run if this file is already present in the system.
