-------------------------------------
Hello [~vaishnavi546]
Thank you for your report.
What happens if you try version 3.13.0?
Do you have a test that reproduces the issue (even if it uses Docker)?
> FTPS File upload fails with "426 Failure reading network stream." on TLS 1.3
> ----------------------------------------------------------------------------
>
> Key: NET-743
> URL: https://issues.apache.org/jira/browse/NET-743
> Project: Commons Net
> Issue Type: Bug
> Components: FTP
> Affects Versions: 3.9.0, 3.10.0, 3.11.0, 3.11.1, 3.12.0, 3.13.0
> Environment: Independent of the OS.
> Apache Commons Net: 3.9.0(Issue is present in 3.13.0)
> FTPS Server: vsftpd
> Protocol: FTPES with TLSv1.3
> Java Version:
> java 1.8.0_481-b25
>
> Reporter: vaishnavi pathipati
> Priority: Critical
>
> When using Apache Commons Net 3.9.0 to upload files to a vsftpd FTPS server
> over TLSv1.3, file uploads fail intermittently with a 426 Failure reading
> network stream error. The issue is observed only with TLSv1.3 and does not
> occur with TLSv1.2. The failures are non-deterministic — there is no
> correlation between specific files, servers, or upload attempts.
> Methods used for upload:
>
> ftpesClient.storeFile(); // primary method for storing files
> ftpesClient.appendFile(); // used for transfer-only (no storage)
>
> Observed behavior:
>
> File uploads fail intermittently on certain servers with low network latency
>
> Our application has different options for failed files to be re-uploaded,
> Noticed that there are several uploads of the same file, and when the last
> upload is successful the size of the file is larger than previous attempts.
>
> The issue is reproducible only with TLSv1.3; TLSv1.2 works without errors
>
> vsftpd server logs:
>
> DEBUG: Client "x.x.x.x", "DATA connection terminated without SSL shutdown.
> Buggy client! Integrity of upload cannot be asserted."
> DEBUG: Client "x.x.x.x", "SSL shutdown state is: NONE"
> DEBUG: Client "x.x.x.x", "SSL shutdown state is: NONE"
> DEBUG: Client "x.x.x.x", "SSL ret: 18446744073709551615, SSL error:
> error:0A000126:SSL routines::unexpected eof while reading, errno: 0"
> FTP response: Client "x.x.x.x", "426 Failure reading network stream."
> This issue looks similar to the below issue.
