I can't add the ip address of my jump server to known hosts of ssh

[Ker Tenepere]

I'm making a pipeline where I need to connect from bitbucket pipelines to jump server inside of a bastion host server. The problem is Known Host in SSH isn't accepting my jump server's ip address.

Repository > Repository Settings > SSH Keys > Known Hosts

Known Host only accepts the ip address of bastion host server, the problem is it doesnt accept servers inside of bastion server.

Example:

Bastion Server IP: 54.222.222.11

Bation Server PORT: 8888

Jump Server IP: 172.222.222.1

Working format

54.222.222.11:8888 # Known Host accepts this format for bastion Host

Not working

172.222.222.1

54.222.222.11:8888 172.222.222.1

54.222.222.11 8888 172.222.222.1

172.222.222.1 54.222.222.11:8888 

54.222.222.11:8888,172.222.222.1

54.222.222.11:8888-172.222.222.1

Please Help me

From Repository's Pipeline, I'm trying to connect to Jump Server.

I know this works because in my local machine, I can connect directly to Jump Server.
