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.

(local?) firewall?

I was told by the sysadmin it is not the firewall.

If you can ping them there is a route.. nothing funny in the hosts firewall? Can you post the output of pfctl -sr

I can't ssh to any hosts from this OpenBSD server at all. But I can ssh to all these other hosts from my Linux machine or other BSD or windows machines.
Code:
~ pfctl -sr
pfctl: /dev/pf: Permission denied
