IOS XE on CSR Recommended Code AlwaysOn - Connection Reset by peer

[barweiss]

Hello,

Just a heads up :), I was doing some yang testing this morning on sandbox-iosxe-recomm-1.cisco.com. Unable to connect via ssh on port 22 and get:

kex_exchange_identification: read: Connection reset by peer

Also NETCONF attempts fail as well, here is the error (I was running a demo scipt from https://github.com/CiscoDevNet/netprog_basics/network_device_apis/yang/example.py :

ConnectionResetError: [Errno 54] Connection reset by peer

Thanks!

Barry

It appears to not be working again.

IOS XE on Catalyst Always On : sandbox-iosxe-latest-1.cisco.com is returning kex_exchange_identification: read: Connection reset by peer Connection reset by 131.226.217.143 port 22

What is the fix for this? 

[bigevilbeard]

@sean.hutcherson This error typically points to a network connectivity or version compatibility issue. Cisco team will need to look into this to fix.

Hope this helps.

The team is working on this.

FYI:  The device is now accessible but the password credential is not working.
