Suddenly getting an error "Credential is not correct" Amazon SSM

Hi,

We are suddenly getting an error "Credential is not correct" in Amazon SSM Logs. Our Cloudwatch custom metrics have stopped working. We have not changed anything and also made sure that SSM Role is attached to that instance. We also tried to put credential file in the server on .aws folder on the windows server. PSB Actual error getting in log file "amazon-ssm-cloudwatch.log".

Credential is not correct. Setting CloudWatchService IsImpaired to be true, Failed to upload metric to CloudWatch. Amazon.CloudWatch.AmazonCloudWatchException: Amazon CloudWatch Metrics no longer supports TLS 1.0 and TLS 1.1 connections. You must update your client to use TLS version 1.2 or above.
