Hello,
I am trying to access my Cat9k-Always-On sandbox instance using my credentials, but I keep getting connection timed-out errors. I even tried to ping the hostname, but the request was timed out. I have verified that the instance is active and running but I am unable to access it.
Solved! Go to Solution.

@aravindskn given your error, "Network error: Software caused connection abort" message in PuTTY you shared. The error usually indicates that the connection was actively terminated by something on your computer rather than a simple timeout due to no response from the end device. Is there any firewall, software (local or corp) which might be preventing this connection?
You could try a curl from your command line to test connection to see if this connects ok.

@aravindskn how are you trying to access? Check your details in the quick access tab, seems ok here using ssh

@aravindskn double checked your hostname/IP address in SecureCRT and PuTTY, its easy to make a typo, is this using ssh here on port 22, it should default to this, but worth checking.

@bigevilbeard Yes, I have checked my hostname and credentials, but it doesn't seem to work.

@bigevilbeard I think my computer blocked the traffic. I tried SSH through another computer, and I was able to access the sandbox.
Thank you, @bigevilbeard, for the help!
