Odd problem with ftp

    I have discovered a problem that has just appeared and it's very specific. I use WS_FTP pro and I can no longer see the directory listing nor can I upload files to one server. My other server is fine and there's no issue. It's only the newer server which is running a higher php version.

    The problem does not exist if I use filezilla so I know that the server is okay. And though it would appear to be a ws-ftp problem, I don't have the same thing happen when accessing my other server. My thought is that there has been a small change on the server that started this problem.

    I can find no information on the ipswitch website and they want me to pay for another year of support in order to answer my questions. I have always used ws_ftp pro - for at least 15 years and really don't want to pay more money on top of what I have paid over the years. So I'm hoping someone might have an idea of what may have happened.

    I'm running WHM 11.52.0 (build 9) and do automatic updates and this may have happened in the past ten days. No changes have been made on the server during the same time.

    Any insights would be welcome.

    We just got it working this morning. Still not really sure what it was. One of my server techs was using the same software and didn't have a problem but he made some tweak on the server and it all started working again. And no, I don't know exactly what he did either. The whole thing was really weird.

    I am happy to see the issue is now resolved. It's likely firewall rules that were blocking passive FTP connections.

    Thank you.

    No, it wasn't - cause someone could manage with the same software.

    It's very possible that it was another cause, but that's the most common reason for compatibility issues with certain FTP clients (some clients force the use of passive mode) for any other users who visit this thread and experience the same problem. In any event, I am happy to see the issue is no longer occurring. Let us know if you encounter any additional issues.

    Thank you.

    I'm seeing this same issue with version 12.4 of WS_FTP Professional. Start with the latest update. First on one server, then when it updated, the other. The problem exists with FTP/SSL [AUTH SSL] version. Using passive, even forcing passive, does not work at all. Other FTP programs (Goodsync, PHPEd & Dreamweaver) seem to work fine. WS_FTP will work in SFTP/SSH mode with a keypair.

    Obviously passive transfers still work, I verified my passive range and firewall settings, plus other programs still work fine. Log says this in WS_FTP:
    Code:
