Hi there & welcome,

This is most likely because tunneling is disabled in /etc/ssh/sshd_config. Look at the PermitTunnel option, which has a default value of "no".

Good luck!

You have not mention what operating system you are using ? what you have tried to get these error out ? Anyway if you are trying with Centos/Rhel distro of operating system enable portforwarding

vi /etc/ssh/sshd_config

AllowTcpForwarding yes
