I have over 10 Azure Web Apps for which i've been able to manually upload file to using FTPS for over 3 years. Now all of a sudden on Mac Client and Win10 client and other peoples computers we're all getting the same errors preventing manual access. This happens across multiple subscriptions as well. As far as i'm aware the pipeline is still releasing with ZipDeploy without any issues so this seems to be a FTP/FTPS only issue.

  • Just in case of recent changes I followed the instructions on https://learn.microsoft.com/en-us/azure/app-service/deploy-ftp and both App and User credentials failed to work while connecting with FTPS – A. Wentzel Jan 17 '19 at 02:33

Firstly, reconnect with FTP and FTPS both ways, sometime these connections are not stable, just delete the "s" in FTPS endpoint you will get the FTP endpoint.

If it still fail you could go to your application settings and check whether your FTP access is Disable. enter image description here

Check the time-out setting, set this in FileZilla client, go to Edit, Settings, Connection, FTP, and check "Send FTP keep-alive commands" checkbox.

If all these couldn't solve it, please configure firewall setting.

Hope this could help you, if you still have other questions, please let me know.

  • Thanks for your suggestion George. It looks like it's currently an issue only when on Microsoft's Campus. I will update again when I know the exact details. – A. Wentzel Jan 17 '19 at 16:17

Turns out a patch was required for the Switch being used across the network. IT updated a bunch of the switches and this issue resolved itself.
