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.

Hey Ker,

Just stepping in here as I have noticed that you have yet to receive a response from our community.

A common issue that can occur when adding the IP address to your known hosts in the Bitbucket Cloud UI is that the IP address is being blocked somewhere by the server.

Can you please make sure you whitelist the following IP addresses from the link below - and also ensure port 22 is open on them and let me know how this goes:
