Hallo,

I am currently experiencing this error: Cannot connect SFTP server: An established connection was aborted by the server.

I double checked that the password is correct (encryption lead to the same secret value twice).

What can I do to debug this?

   Are you deploying from a build or deployment environment?

   The configuration is in my appveyor.yaml, so I guess it is from a build environment?

   It could be some incompatibility or lack of features in SFTP library used by AppVeyor build agent. .NET implementation of SFTP has been always behind the latest standards.

   I'd like to recommend you configuring WinSCP for SFTP uploads: https://help.appveyor.com/discussions/problems/33606-try-to-deploy-...

   Thanks. Your tip helped, my deploy_scripts now look like this:

   Windows
   deploy_script:
   - cmd: |
   choco install -y winscp
   echo open sftp://appveyor:%DEPLOY_PASS%@<ssh-server>/ -hostkey="<hostkey (shown when running without this option)>" > ftp.txt
   echo put installer\* %deploy_prefix%build/ >> ftp.txt
   echo exit >> ftp.txt
   "C:\Program Files (x86)\WinSCP\winscp.com" /script=ftp.txt
   Linux
   deploy_script:
   - sh: |
   sudo apt-get -y install sshpass
   ssh-keygen -f "/home/appveyor/.ssh/known_hosts" -R "<ssh-server>"
   printf "%s" "$DEPLOY_PASS" >/tmp/deploy_password
   sshpass -f "/tmp/deploy_password" scp -r installer/* appveyor@<ssh-server>:${deploy_prefix}build/
   Mac OS X
   deploy_script:
   - sh: |
   brew install sshpass
   ssh-keygen -f "/Users/appveyor/.ssh/known_hosts" -R "<ssh-server>"
   printf "%s" "$DEPLOY_PASS" >/tmp/deploy_password
   sshpass -f "/tmp/deploy_password" scp -r installer/* appveyor@<ssh-server>:${deploy_prefix}build/
   Maybe this is also helpful for others?

   Thanks Heiko
