Can't ssh to always on NX-OS Programmability sandbox

[NBenat]

Struggling with this connectivity issue: Putty, Windows 10, ssh to sandbox-nxos-1.cisco.com, tried port 22 and 8181. I get a Putty fatal error: Network error: Connection timed out.

An nslookup to sandbox-nxos-1.cisco.com does give me an IP address. Ping fails. On the lab workspace, I see

"SANDBOX LAB(RESERVE TO ACTIVATE) as shown below. Is there something I need to do and if so, would that help fixing the connectivity issue? Any suggestion is welcome. Thank you in advance.

Hello @NBenat this looks like an issue with the sandbox, not your side. I have raised this with our team to take a look. Thanks for reporting this.

Hello Bigevilbeard,

Thank you for addressing. I just tried and had no more connectivity issue.

[abyf29041987]

I am facing the same issue. Can you please tell me how to overcome it? 

 

[bigevilbeard]

@abyf29041987 you have the wrong destination hostname this should be sandbox-nxos-1.cisco.com

See the sandbox details here --> https://devnetsandbox.cisco.com/RM/Diagram/Index/dae38dd8-e8ee-4d7c-a21c-6036bed7a804?diagramType=Topology

Hope this helps.
