Amazon S3: Region is not configurable

2018-05-03 17:30

See attachment for error. The region key is not correct, and there is no way for me to specifiy it. Note that this occurs when using AWS GovCloud, which is isolated from normal AWS services.

Text of screenshot:

The authorization header is malformed; the region 'us-east-1' is wrong; expecting 'us-gov-west-1'

Extra Details: Region: us-gov-west-1, RequestId: AB3CB4671E441F7A, HostId: <...>
Connection failed.

Please attach a full session log file showing the problem (using the latest version of WinSCP).

To generate the session log file, enable logging, log in to your server and do the operation and only the operation that causes the error. Submit the log with your post as an attachment. Note that passwords and passphrases not stored in the log. You may want to remove other data you consider sensitive though, such as host names, IP addresses, account names or file names (unless they are relevant to the problem). If you do not want to post the log publicly, you can mark the attachment as private.

steps to replicate

2018-05-09 12:53

1) Turn on session logging
2) Connect to the regular AWS S3 service
3) search the session log for the line (near the top of the file): "S3: Default region: us-east-1"

Update WinSCP so we can configure the Default Region variable. Receive donation.

Using the latest version (5.13.4), I've tried overriding the default region with the "S3DefaultRegion" raw session setting (as noted in changelog for version 5.12.1):

open ... -rawsettings S3DefaultRegion=eu-central-1

According to the log, the setting is applied, however I get the same error when trying to connect via scripting (see attached log #1).

When I use a stored session (with Hostname set to another region, e.g., "s3.eu-central-1.amazonaws.com"), no error appears and I connect successfully (see attached log #2).

Note that I am using the portable version of WinSCP.

Your stored session has the bucket set as initial remote directory. While the other script tries to access a root folder (bucket list).
Add the bucket to URL:

open s3://***:***@s3.eu-central-1.amazonaws.com/bucket/ -rawsettings S3DefaultRegion="eu-central-1"

Not working for s3 c# assembly

2019-02-07 15:48

Hi I am using winscp 5.13.7 in c# code.

I have tried multiple options but it keeps giving me the error. I need to connect to us-west-2 region with initial bucket. It keeps giving me the bucket issue.
1.

SessionOptions sessionOptions = new SessionOptions
                {
                    Protocol = WinSCP.Protocol.S3,
                    HostName = bucketName + ".s3-us-west-2.amazonaws.com" ,
                    PortNumber = 443,
                    UserName = ConfigurationManager.AppSettings["AWSAccessKey"],
                    Password = ConfigurationManager.AppSettings["AWSSecretKey"]
                };
                using (Session session = new Session())
                {
                    sessionOptions.AddRawSettings("S3DefaultRegion", "us-west-2");
                    // Connect
                    session.Open(sessionOptions);

2. using ParseUrl method but with s3.region

sessionOptions.ParseUrl("s3://user:pwd@s3.us-west-2.amazonaws.com/bucket/");
                    sessionOptions.AddRawSettings("S3DefaultRegion", "us-west-2");
                    // Connect
                    session.Open(sessionOptions);

3. using ParseUrl method but with s3-region

sessionOptions.ParseUrl("s3://user:pwd@s3-us-west-2.amazonaws.com/bucket/");
                    sessionOptions.AddRawSettings("S3DefaultRegion", "us-west-2");
                    // Connect
                    session.Open(sessionOptions);

4. 3. using ParseUrl method

sessionOptions.ParseUrl("s3://user:pwd@bucket.s3-us-west-2.amazonaws.com");
                    sessionOptions.AddRawSettings("S3DefaultRegion", "us-west-2");
                    // Connect
                    session.Open(sessionOptions);

It always throws an error about us-east-1 being used instead of us-west-2.

1) Don't change hostname.
2) Please attach a full session log file showing the problem (using the latest version of WinSCP).

To generate the session log file, set Session.SessionLogPath. Submit the log with your post as an attachment. Note that passwords and passphrases not stored in the log. You may want to remove other data you consider sensitive though, such as host names, IP addresses, account names or file names (unless they are relevant to the problem).
