6 years ago There appears to be a commonality between FTP issues and Azure Deploy issues which points to possibly a Publisher. Who is actively investigating the FTP / Azure Deploy issue? Please provide status?
Some additional details from Suwat B: We picked a few incidents and looked at the server-side log (\suwatchhv3\public\fluentweb_ftp.log). The failure happened when FTP server tried to handle to PASV (passive request for DataChannel port). From the log (which was quite consistent for various incidents) after receiving > hundred files, the FTP server ran into issue where it can’t open/listen to a port (in this case, always 10055!) for PASV request and failed with error 10013 (WSAEACCESS). Unfortunately, we still don’t know why at this point. We don’t want to rule out whether it was client or server sides.

This seems to be an issue that’s been dealt with before. https://serverfault.com/questions/527322/problems-configuring-filezilla-ftp-server-on-windows-azure-virtual-machine

Issue Description
Our CD Build consistently fails during FTP process to an Azure Web App. We started getting consistent failures on 11/20/2017, prior to that we had not had any issues with the FTP process.
To circumvent the issue, we are able to FTP the project files through other clients like FileZilla and have not seen any issues with those programs.
The VSTS FTP process successfully uploads some files, however it inevitably fails with the below error. The specific file that is causing the failure is not consistent between builds.
