Description: Hi all,

I have an issue when accessing LAB using ssh.
When trying the access LAB using ssh, it failed with error below:

~~~
$ ssh -i ~/.ssh/rht_classroom_rh415.rsa -J cloud-user@52.118.39.251:22022 student@172.25.252.1 -p 53009
channel 0: open failed: administratively prohibited: open failed
stdio forwarding failed
kex_exchange_identification: Connection closed by remote host
~~~

Could you please check what causes this?

Note that I have followed KB article below but no luck.
