Hi, Im new to nginx and am trying to load-balance ssh sessions to an autoscaling group of ECS instances in AWS. Having trouble getting my config files right. I dont get any errors on startup, but my access.logs shows this lines for each attempt and the command line gives me this : ssh [ec2-user@10.172.60.7](mailto:ec2-user@10.172.60.7) ssh\_exchange\_identification: Connection closed by remote host Access.log: 10.172.200.18 - - [31/Jul/2015:15:54:15 +0000] “SSH-2.0-OpenSSH\_6.2” 400 173 “-” “-” “-” 10.172.200.18 - - [31/Jul/2015:16:25:31 +0000] “SSH-2.0-OpenSSH\_6.2” 400 173 “-” “-” “-” 10.172.200.18 - - [31/Jul/2015:16:34:31 +0000] “SSH-2.0-OpenSSH\_6.2” 400 173 “-” “-” “-” Any direction would be appreciated.

Looks you are trying to balance ssh connections using http module. This won’t work, as http is only able to balance http requests, not arbitrary connections. If you want to balance ssh connections, try using the stream module instead: > **[Module ngx\_stream\_core\_module](http://nginx.org/en/docs/stream/ngx_stream_core_module.html)** > **[F5 NGINX: Built for cloud-native apps.

The stream module is designed to balance arbitrary connections, and should work for you. > This communication is Confidential Information.
