Fix AWS CLI AuthFailure - Validate with access credentials


This error is mostly occured due to wrong credendials or wrong date and time set on the server.

Error:

"An error occurred (AuthFailure) when calling the DescribeInstances operation: AWS was not able to validate the provided access credentials".

Lets get started.

Check 1 : Verify the aws_access_key_id and aws_secret_access_key

Assume that you have configured your system to manage your AWS Services from AWS CLI command using "aws configure" command. Once it is done, you must have a credential file generated in your home directory.

[root@learnitguide.net ~]# cat /root/.aws/credentials
[default]
aws_access_key_id = AKIAI6MXBHOVEDJM77DA
aws_secret_access_key = wTPWr2rUview0axamwgMCc3qkydIjPmhgbRyK3Mn

Make sure the "aws_access_key_id" and "aws_secret_access_key" are correct as taken from IAM of AWS or create a new access key from IAM and change it accordingly in the credential file.

Check 2 : Verify the current date / time

Ensure the current date and time set on the server is correct or not.

[root@learnitguide.net ~]# date
Wed Apr 17 21:12:25 IST 2018
[root@learnitguide.net ~]#

If it is not correct, change it to current date and time as below.

Syntax: date MMDDhhmmYYYY

For example, today date is 04/18/2018 and time is 14:30 IST.

[root@learnitguide.net ~]# date 041814302018

Above solution would help you to fix AWS authfailure error.
