SocketTimeoutException: connect timed out at org. SocketTimeoutException: connect timed out at java. Dec 19, PM com. InvocationTargetException at sun. AWSIotException at com. Error code: 7. Hi kuncao. Connecting with the same client id in different MQTT connections is not allowed.
The next connection will kick out the first connection. In IoT Console. Mqtt connection lost. Hello kuncao. It seems like you are seeing two issues. For the first, it looks like you are receiving a socket timeout. Can you confirm you are able to connect to your endpoint outside of using the Java SDK? Note, your region in the previous example may differ. For the second, when does this error appear? Does it appear on first connect? Are you able to consistently connect and then receive this error after a certain amount of time?
Is an action required such as switching pages required to see the error?GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together. Have a question about this project?

I've found similar older bug reports which were closed after having been fixed. For me this bug is real right now running aws-sdk 2. Idle connections will be closed. Sometimes reuploading helps. But some files are rejected in this way even 10 times while others work.
BjoernRuberg can you share the code that you are using? AdityaManohar sure. This is the extracted code:. I now got the reason why reuploads did not work. The stream I used was finished after first upload and would never have transferred any new data for the next attempts. But I still see a problem with putObject that it can fail at the first attempt.
I now use ManagedUpload which seems to not have the problem. If you are using AWS. I'm going to mark this as closed since you already seem to have it working with AWS.

Note: API calls can take longer than expected when network connection issues occur. Network issues can also cause retries and duplicated API requests. To prepare for these occurrences, your Lambda function must always be idempotent. Here are the default values of these settings:. To fix the retry and timeout issues, review the logs of the API call to find the problem. Then, change the retry count and timeout settings of the SDK as needed for each use case.
To allow enough time for a response to the API call, add time to the Lambda function timeout setting. Using Amazon CloudWatch Logs, you can get details about failed connections and a count of attempted retries. In this example error log, the connection was successful, but it timed out after the response took too long connection timeout :.
Note: These logs aren't generated if the API call doesn't get a response within your Lambda function's timeout. If the execution ends because of a function timeout, try one of the following:. To determine the right values for each setting, test different configurations and get the following information:.
Note: Before using any of the following example commands, replace the example values for each setting with the values for your use case. A low Lambda function timeout can cause healthy connections to be dropped prematurely. If that's happening in your use case, increase the function timeout setting to allow enough time for your API call to get a response.
Use this formula to estimate the base time needed for the function timeout:. For example, say that the SDK is configured for 3 retries, a connection timeout of 10 seconds, and a socket timeout of 30 seconds.
In that case, your Lambda function timeout should be at least seconds:. Add an additional margin of time for example, 20 seconds to handle the rest of the code execution:. AWS Lambda Limits. Last updated: These issues can occur when: You call a remote API that takes too long to respond or that is unreachable.

See here: AWS Documentation. The connection timeout is the amount of time in milliseconds that the HTTP connection will wait to establish a connection before giving up.
The default is 50, ms. To set this value yourself, use the ClientConfiguration. If I am calling an external lambda function, I can configure this before I make the call. This is what all of the documentation is showing examples of. Is there a way I can add an environment variable or programmatically update the current AWS Lambda Java function connection and socket timeout from within itself? There is not a "client" invoking this lambda function. It is intended to be scheduled on the hour, triggered by the event type "CloudWatch Events - Schedule.
The overall lambda time is currently extended to 5 minutes. The lambda's GET call fails right at the 50 second mark. The provided AWS documentation above references a default 50 second limit, with 3 retry attempts, both of which supposedly can be modified. However, I have been unable to modify the connection or socket timeout programmatically from the lambda's own code, or any parameter on the lambda itself. There has to be a way to configure this properly.
I fed it proxy settings and I verified the connection was correct and that it was the right call. I found the issue. It turns out the lambda was successful from the AWS console.However, I'm getting the following error: Your socket connection to the server was not read from or written to within the timeout period. Idle connections will be closed. When the connection between the client and the Amazon S3 server remains idle for 20 seconds or longer, Amazon S3 closes the connection.
This results in the RequestTimeout error.
How do I troubleshoot retry and timeout issues when invoking a Lambda function using an AWS SDK?
To troubleshoot this error, check the following:. The number of bytes set in the "Content-Length" header is more than the actual file size. If the expected amount of data isn't received by Amazon S3, and the connection is idle for 20 seconds or longer, then the connection is closed.
Be sure to verify that the actual file size that you're sending to Amazon S3 aligns with the file size that is specified in the Content-Length header. If a few packets or all packets are dropped because of a slow or poor network connection, then Amazon S3 waits for the expected number of bytes to be received. If the connection is idle for 20 seconds or longer, then Amazon S3 closes the connection and returns the RequestTimeout error. To verify whether this is causing the error, perform a packet capture and check for any packet drops.
How can I troubleshoot the error "Your socket connection to the server was not read from or written to within the timeout period" from Amazon S3? Last updated: To troubleshoot this error, check the following: The number of bytes set in the "Content-Length" header is more than the actual file size When you send an HTTP request to Amazon S3, Amazon S3 expects to receive the amount of data specified in the Content-Length header.
Network issues like high latency, packet loss, and congestion If a few packets or all packets are dropped because of a slow or poor network connection, then Amazon S3 waits for the expected number of bytes to be received.

Each of the configurable values has a default value defined by a constant. Set the maximum connections to the number of concurrent transactions to avoid connection contentions and poor performance.
The connection timeout is the amount of time in milliseconds that the HTTP connection will wait to establish a connection before giving up. The default is 10, ms. To set this value yourself, use the ClientConfiguration.
In failure situations where a connection is established to a server that has been brought out of service, having a finite TTL can help with application recovery. The default maximum retry count for retriable errors is 3. You can set a different value by using the ClientConfiguration. The majority of users will never need to tweak these values, but they are provided for advanced users. Optimal TCP buffer sizes for an application are highly dependent on network and operating system configuration and capabilities.
For example, most modern operating systems provide auto-tuning logic for TCP buffer sizes. This can have a big impact on performance for TCP connections that are held open long enough for the auto-tuning to optimize buffer sizes. Large buffer sizes e.
This is only a hintand the operating system might not to honor it. Many resources are available to help with configuring TCP buffer sizes and operating system-specific TCP settings, including the following:.

If the default values for retries and timeouts are not appropriate for your application, you can adjust them for your specific requirements, but it is important to understand how doing so will affect the behavior of your application.
Do you want the call to fail fast, or is it appropriate for the call to keep retrying on your behalf? Is your application a user-facing application or website that must be responsive, or is it a background processing job that has more tolerance for increased latencies?
Is the application deployed on a reliable network with low latency, or it is deployed at a remote location with unreliable connectivity? The SDK will retry requests that fail due to server-side throttling or dropped connections. You can use the MaxErrorRetry property of the ClientConfig class to specify the number of retries at the service client level. The SDK will retry the operation the specified number of times before failing and throwing an exception. When a retry occurs, it increases the latency of your request.
You should configure your retries based on your application limits for total request latency and error rates. These values are specified in the Timeout and the ReadWriteTimeout properties of the ClientConfig class, respectively.
By default, the Timeout value is seconds and the ReadWriteTimeout value is seconds. When your network has high latency, or conditions exist that cause an operation to be retried, using long timeout values and a high number of retries can cause some SDK operations to seem unresponsive.
Timeout and ReadWriteTimeout are set to the maximum values if the method being called uploads a stream, such as AmazonS3Client.
