Silicon Mode Errors on FTP with TLS Login (7 posts)

    When I try to connect to my FTP server on my new Silicon iMac in native mode, it errors because it tries to connect using AUTH GSSAPI and fails. When I click the Get Info box making it run in Rosetta, it connects properly using AUTH TLS the first time, every time. Reproducible. Mac OS 11.5.1.

    HERE IS THE ERROR TRANSCRIPT (WITH DOMAIN XXXXXXXXX):

    Hi,

    Thanks for reporting this problem, and including a transcript. When you connect in native mode, are you using the New Connection window or opening a shortcut or recent connection?

    Thanks,

    Both transcripts were fresh startups of Fetch then clicking on the same shortcut.

    Funny thing... when the error message pops up from attempting the shortcut and failing in Silicon mode, the resulting New Connection window succeeds if tried.

    Also, if connecting via the New Connection window successfully then editing a file, when I go to save that edit (on the FTP server) it fails with the same GSSAPI error. Subsequently saving the file to the desktop then dragging a file into the window always succeeds however.

    There appear to be no problems at all if left in Intel Non-Silicon-native mode.

    Hi,

    Could you try option-double-clicking the shortcut? That should bring up an already filled-out New Connection window, where you can confirm that the Connect using menu is set to "FTP with TLS/SSL". Is that what you see?

    Thanks,

    Yes.

    FTP with TLS/SSL (selected)
    Enable encryption (checked)
    Password filled
    Port 21

    Also, even in SIlicon mode, if I use the resulting dialog box that is presented from holding down option-and selecting my shortcut, it works! Clicking the shortcut directly again fails.

    Hi Greg,

    That's very helpful information, thanks! It sounds like there's a bug in the way Fetch's Apple Silicon native code is storing and/or loading connection information from shortcuts. I'll investigate further.

    Thanks again,
