kex_exchange_identification: read: Connection reset by peer

I am running through this lab "Exploring IOS XE YANG Data Models with NETCONF"

when I try this command to ssh to the CSR1000V Host (sandbox-iosxe-recomm-1.cisco.com), 

ssh -oHostKeyAlgorithms=+ssh-dss developer@sandbox-iosxe-recomm-1.cisco.com -p 830 -s netconf

 

The response is always:

kex_exchange_identification: read: Connection reset by peer

 

Is there anything wrong with my command?

Ok, I try this host CSR1000v Host: sandbox-iosxe-latest-1.cisco.com and it works.

@EvanC you command is correct - i am unsure why there is such difference between the two XE device, i saw the same with REST also.

There's something definitely wrong with the lab. The host does not answer on ssh protocol, accessing it on https protocol gives nginx error "gateway timeout".

Cisco, please check the CSR.

 

@mschedrin i have checked this as of time 2:35 PM Thursday, July 22, 2021 Coordinated Universal Time (UTC) via ssh.

Welcome to the DevNet Sandbox for CSR1000v and IOS XE

The following programmability features are already enabled:
  - NETCONF
  - RESTCONF

Thanks for stopping by.

Right, ssh and netconf works now, however webinterface and restconf on port 443 still reply "502 Bad Gateway
nginx/1.13.12". I guess it's not supposed to be like that.

 

@mschedrin as noted above this version is showing issues when using RESTCONF. Recommend to use https://devnetsandbox.cisco.com/RM/Diagram/Index/7b4d4209-a17c-4bc3-9b38-f15184e53a94?diagramType=Topology 

 

Hope this helps.
