Can't establish outbound ssh connection on an OpenBSD system

I am getting the below error when I try to make outbound ssh from an OpenBSD system. I can't ssh to any host except the localhost. I can ping the hosts which I can't ssh, though.
Code:
~ uname -rs
OpenBSD 6.1
~ ssh -V       
OpenSSH_7.5, LibreSSL 2.5.2
~ ssh hostname
ssh: connect to host hostname port 22: No route to host

I can ssh to hostname from other Linux or BSD machines without any problem.

NAME
ssh-argv0 -- replaces the old ssh command-name as hostname handling SYNOPSIS
hostname | user@hostname [-l login_name] [command] hostname | user@hostname [-afgknqstvxACNTX1246] [-b bind_address] [-c cipher_spec] [-e escape_char] [-i identity_file] [-l login_name] [-m mac_spec] [-o option] [-p port] [-F configfile] [-L port:host:hostport] [-R port:host:hostport] [-D port] [command] DESCRIPTION
