Received empty VPN credentials

I'm getting empty VPN credentials by email: 

Screenshot From 2026-07-30 16-40-38.png

I tried with 'sandbox-iosxr-1.cisco.com', as I see in the I/O tab (image attached) but the authentication is failing.
This is happening with the IOS XR Always-on Sandbox.

@fandre207 I confirm the credentials are not on the mail, I'll share this with the sandbox team. However as you noted the credentials can be found in the I/O tab. 

I can see the ssh connection to the sandbox is not working as you commented, I'll the sandbox team to reset it.

@Jesus Illescas Should I use the ssh connection to establish the lab's private VPN?

I understand that these are different URLs but please correct me if I'm wrong. 

I tried re-launching and Lab Network Address is missing on the email.

@fandre207 the Always On sandboxes don't require VPN, you can ssh directly. However, I can see the sandbox is not working at the moment. It can take a moment for the sandbox team to see my request. 

The mail needs some rework, I can see is confusing, but the credentials that don't appear on the mail are the same as the ones in the I/O tab in the environment page.

Hello @Jesus Illescas , 

Do you have any news from the sandbox team on the IOS XR Always? I see is still down.

I also see this ones are down: 
- Catalyst 8000 Always-On Sandbox
- Nexus 9000 AlwaysOn Sandbox

I understand is best effort to fix it but could ask the team?

Hi @fandre207 I see the sandboxes XR and C8k Always On are not working correctly, I will ping again the sandbox team. Thanks for sharing.

I tested the N9k always on too, but this one is working for me right now. If you have an active reservation, please end it and start a new one.

Hi @Jesus Illescas , I started a fresh new reservation for N9k always-on but is not working right now: 

labs
labs ping sbx-nxos-mgmt.cisco.com
PING sandbox-nxos-1.cisco.com (131.226.217.151) 56(84) bytes of data.
^C
--- sandbox-nxos-1.cisco.com ping statistics ---

labs ssh [email protected]

Received disconnect from 131.226.217.151 port 22:2: Too many authentication failures

The error message indicates that my user had too many authentication failures. Could you ask the team if the problem is with my particular username "felix.andre86" ? 

Anyway ping is not responding... so I assume is down again.

@fandre207 I tested the nexus always on and worked for me.

Is felix.andre86 the user that appears on the environment page? a screenshot helps. Sometimes the credentials might fail at the first attempt, if that happens end and start a new reservation.

Also, please share the output of your ssh command using the -v flag (assuming openSSH) or equivalent.

ssh <YOUR_USER>@sbx-nxos-mgmt.cisco.com -v

It would be strange that the issue might be only for your username.

About ping, as far as I know is disabled for all always on sandboxes.
