blob

Which version of the SDK was used?

1.5.2

What's the PHP/OS version?

root@4f741507c90e:/app# lsb_release -a No LSB modules are available. Distributor ID: Debian Description: Debian GNU/Linux 10 (buster) Release: 10 Codename: buster Env: Docker

What problem was encountered?

cURL error 56: OpenSSL SSL_read: SSL_ERROR_SYSCALL, errno 104 (see https://curl.haxx.se/libcurl/c/libcurl-errors.html)

Steps to reproduce the issue?

We are using flysystem-azure-adapter. After investigating there it seems that the proxy works fine but the SDK throws an error. I am trying to upload a file (1.5G) which causes the error. Smaller files work correct

Have you found a mitigation/solution?

No

Is there a failing request ID related to this problem returned by server? What is it?

No

After doing my own debugging on the SDK itself it seems that some chunks fail to process. At the end when one of the chunks has failed all is returns as an error. Seems that chunks that fail also do not retry?
