IOS XE on Cat8kv AlwaysOn NOT working for days!

[Rakibul Hassan]

>ssh admin@devnetsandboxiosxe.cisco.com
kex_exchange_identification: read: Connection reset

I can't connect through Postman. It says Bad gateway 502.

I was using GET https://devnetsandboxiosxe.cisco.com:443/restconf/data/ietf-interfaces:interfaces,

the response was, 

>502 Bad Gateway
What should I do?

It was ok yesterday when I logged in, sadly this sandbox like a few of the other always on, gets some abuse and others get locked out. Can you access the sandbox with ssh?

The service in domain devnetsandboxiosxe.cisco.com is recovered.

It seems to be down again? Can't access via SSH either:
ssh admin@devnetsandboxiosxe.cisco.com
Connection closed by 131.226.217.181 port 22

[zowu]

We've reloaded the cat8k and the access is back now.

It seems down again, after indeed working for +/- a day. Can it be hardened more to avoid abuse? Or have some form of availability tests run against it and have it recover when unavailable?

@jvameyde Only way for this to happen is to make the device read only, which would not be of much use IMO. Suggest to use the reservation one when/if the always on is down, or for simple tested spin up a CSR in a virtual box on your local machine. I made a simple test to check in streamlit https://github.com/bigevilbeard/streamlit_demo which you can run locally to see if the devices are up and functioning.

Hope this helps.
