Deactivation of the ssh service after fifty continuous connections

we write a script for connecting a windows server using ssh. we should sending 200 command, from loop. but, ssh service stopped after 50 connection. disable firewall, changing port, restarting ssh, but it did not work. just, we should restarting a windows server after, script running in 50 connection.

if ssh, have a limitation configuration or security, config for this, how we can disable them or resolve this issue.
