AWS Snowball will not unlock and cant access.

Question

I just ordered a AWS snowball edge device and downloaded my manifest file and access code. I am using the following method to connect:

snowballEdge unlock-device --endpoint https://x.x.x.x --manifest-file c:\users\administrator\Downloads\xxx_manifest.bin --unlock-code xxx

However, I keep getting the following error message::
SdkClientException - Unable to execute HTTP request: Connect to x.x.x.x.:90
91 [/x.x.x.x] failed: Connection refused: connect

I have validate network connectivity as well so any help is appreciated.

Answer

Make sure you are not blocked by your firewall with http/https request. 
Please follow the process of unloking using the documents below

Answer

Ran into this same error, turned out to be an IP conflict on the network.

Answer

So I was able to solve this by shutting down and waiting 10 mins and then it instantly unlocked. I found another article where it talked about this and that resolution worked.
