n8n - 💡(How to fix) Fix Issues connecting to sftp servers

Describe the problem/error/question

I'm experiencing random errors connecting to sftp server. I have checked the credentials and the connection sometimes works, sometimes fails to verify.

The connection to server works 100% when using standard sftp client like FileZilla

For context, the sftp server I'm connecting to, changed host keys and IP a couple of days ago and we can see it has propagated already:

What is the error message (if any)?

Couldn’t connect with these settings getConnection: getaddrinfo EAI_AGAIN files.autone.io
