Unable to execute HTTP request: Connect to sts.us-east-1.amazonaws.com:443 [sts.us-east-1.amazonaws.com/209.54.177.185] failed: Connect timed out

Sometimes I am getting the below error from sts while API call. I am not able to find the root cause of this error. ``` Unable to execute HTTP request: Connect to sts.us-east-1.amazonaws.com:443 [sts.us-east-1.amazonaws.com/209.54.177.185] failed: Connect timed out ``` Stack Trace JSON ``` { "message": "Unable to execute HTTP request: Connect to sts.us-east-1.amazonaws.com:443 [sts.us-east-1.amazonaws.com/209.54.177.185] failed: Connect timed out", "source": "JavaSDK", "stackTrace": "software.amazon.awssdk.core.exception.SdkClientException$BuilderImpl.build(SdkClientException.java:102)", "cause": { "message": "Connect to sts.us-east-1.amazonaws.com:443 [sts.us-east-1.amazonaws.com/209.54.177.185] failed: Connect timed out", "source": "JavaSDK", "stackTrace": "org.apache.http.impl.conn.DefaultHttpClientConnectionOperator.connect(DefaultHttpClientConnectionOperator.java:151)", "cause": { "message": "Connect timed out", "source": "JavaSDK", "stackTrace": "java.base/sun.nio.ch.NioSocketImpl.timedFinishConnect(NioSocketImpl.java:546)\njava.base/sun.nio.ch.NioSocketImpl.connect(NioSocketImpl.java:597)", "cause": null, "applicationFailureInfo": { "type": "java.net.SocketTimeoutException", "nonRetryable": false, "details": null } }, "applicationFailureInfo": { "type": "org.apache.http.conn.ConnectTimeoutException", "nonRetryable": false, "details": null } }, "applicationFailureInfo": { "type": "software.amazon.awssdk.core.exception.SdkClientException", "nonRetryable": false, "details": null } } ```

API_S3_POST_signature

Hello, i don't arrive to create an post request for create an multpi part upload. Today, i arrive to upload or download a little file on my bucket but, with an upgrade, i would like upload an big file. In the documentation i see this : "https://docs.aws.amazon.com/AmazonS3/latest/API/API_CreateMultipartUpload.html" for create the request, i use this : "https://docs.aws.amazon.com/fr_fr/general/latest/gr/sigv4-signed-request-examples.html" with the different change but, i can arrive to make the request, i have the error "Signature problem" i try different solution but, the result it's the same. Do you havec any solution for fixe my bug, or an other python code ? It's really important for my application. ``` # Copyright 2010-2019 Amazon.com, Inc. or its affiliates.
