Issue connecting to SSH to Starter instance

I am trying to connect to a Starter Web Service instance but I am getting the following error. My ssh client authenticates correctly but then the connection is closed by the server. Here is the Debug log:

Authenticated to (IP address).
debug1: channel 0: new [client-session]
debug1: Entering interactive session.
debug1: pledge: network
debug1: channel 0: free: client-session, nchannels 1
Connection to closed by remote host.
Connection to closed.
Transferred: sent 2120, received 1484 bytes, in 7.2 seconds
Bytes per second: sent 295.3, received 206.7
debug1: Exit status -1

This is probably due to the lack of a running ssh server in my docker instance

Hi there,

There is no requirement for sshd/openssh to be included in your Docker image. I would check our SSH limitations section here to make sure you have met the requirements for SSH to work with Docker on Render.
