Cloud Foundry python app outbound connectivity is not working

[MarioC]

Hello Community!

I have develop a python app that uses the library paramiko to connect via ssh to a remote server, when I run the aplication locacaly on my pc the app runs just fine, however when running the app in a cloud foundry enviroment I get the error paramiko.ssh_exception.NoValidConnectionsError: [Errno None] Unable to connect to port on ip, I dont know if this is because I have to somehow configure the inbound/outbound connection on the cloud foundy environment.

Thanks in advance for your help

Kind Regards

Mario

Do you try to connect to another System in the Internet or via Cloud Connector to On Premise?

Is a connection via internet, when I run it locally I dont use Cloud Connector, just the ssh credentials

[gregorw]

Is it a SSH connection? No HTTP(S)?

Hi Gregor, Yes, the python APP attemps a SSH with the paramiko library but gets the error paramiko.ssh_exception.NoValidConnectionsError

I would suggest that you enable ssh access to your deployed app and then try if you can connect from there via ssh. You might need to use the apt-buildpack to install a ssh client. But I think outgoing ssh connections might be not allowed. Only http(s) connections are possible.
