java.net.ConnectException: Operation timed out (Connection timed out) | Azure blobs

[Neeraj-Srivastav]

I am working oncan application which is to push records to azure table & blobs. My application ran for around 8 days perfectly fine but then it started giving connection time out error related to blob. Can anyone please guide to to workaround this?

Error logs below :

Pretty sparse information you're providing.
We had something similar which was cause by the blob size. As soon as the upload was bigger then ~30 mb we ran into a connection time out too.
We helped ourself by setting the max single upload size:

private static final long MAX_SINGLE_FILE_UPLOAD_SIZE = 30L * 1024 * 1024;
new ParallelTransferOptions().setMaxSingleUploadSizeLong(MAX_SINGLE_FILE_UPLOAD_SIZE);

What is the size of you blobs? maybe this is related
