My bitbucket pipeline can't connect FTP to my server

[Peter van den Ochtend]

When doing a pipeline with the purpose to connect to an ftp server and upload the files I tried to use git ftp for that purpose. (I know there are other ways, but this should work right??)

UPDATE: When I enter not a dns name but my direct IP address it also doesn't work.

There is no filter on the FTP server for incoming connections as far as I know.

Is there a internet filter on Bitbucket in combination with containers/images?

pipeline Log:

I have the following (slimmed down version) yaml:

#First version to create a pipeline to deploy xxx to various servers
image: php:7.4
pipelines:
  branches:
    master:
      - step:
          name: Fill
          script:
            - echo "Please remove this when other steps below are activated"
      - step:
          name: Deploy to test
          deployment: test
       image: samueldebruyn/debian-git
          trigger: manual
          script:
            - apt-get update
            - apt-get -qq install git-ftp
            - git ftp init -vv -u $FTP_USERNAME -p $FTP_PASSWORD $FTP_SERVER

I can connect to it using my client (windows) on my home network and from my company network.

Hi Peter,

Looking at the Pipeline log, I see that there is an attempt to connect to your server via IPv6, which I believe may by the culprit here. At the moment it is not possible to connect via IPv6 from Pipelines:

• https://jira.atlassian.com/browse/BCLOUD-19221

Does this server have an IPv4 address that you can try instead in the git ftp command, and is the connection possible then?

Kind regards,
Theodora

Can someone at least confirm that this type of connection is working for them?
