            Bug ID: 127441
           Summary: LibreOffice hangs (Linux) or gets an error message
                    (Windows) when using documents remotely stored
                    (FTP-protocol)
           Product: LibreOffice
           Version: 6.2.7.1 release
          Hardware: x86-64 (AMD64)
                OS: other
            Status: UNCONFIRMED
          Severity: minor
          Priority: medium
         Component: LibreOffice
          Assignee: libreoffice-bugs at lists.freedesktop.org

Description:
When opening a file from an external location, in my case via FTP, the file
opens correctly and saves correctly when you do that within an amount of time
after login into the remote location. But when a certain amount of time has
passed (can't exactly tell how much time because I don't keep track of that),
and when I save the file remotely, LibreOffice hangs. This is also the case
when you try to open another file remotely stored on this FTP location.

In the case of Windows 10, I get a "error while saving the document" and a
"General input/output error" message. When you close this message, you'll be
able to continue to work with LibreOffice, but when to try opening a remotely
stored file again it ends with the same error message. A workaround is to close
LibreOffice entirely, start the program and open the remotely stored document
once again.

On various Linux distro's I encounter the exact same problem. The only
difference is that I don't get an error message, but LibreOffice freezes and
does nothing anymore. The only thing I can do is to force LibreOffice to quit.

Steps to Reproduce:
1. Open LibreOffice
2. Open an remotely saved document with the FTP-protocol
3. Do the normal routine by logging into the remote storage and select the
desired document (every compatible document will do)
4. Work on your document for a while and try to save it on the same location
where the document is stored

Actual Results:
Under Windows 10: It shows an "error while saving the document" and a "General
input/output error" message. You can continue working with LibreOffice, except
when you try to reopen the remotely stored document once again.

On Linux (Ubuntu 16.04 LTS, Xubuntu 18.04 LTS, Manjaro 18.0.4) the same routine
earlier described results in a freezed LibreOffice. The only way to undo this
is to force to quit the program and to start it again.

Expected Results:
When the remote login time has expired, LibreOffice should ask once again for a
password to log in and to open/store the document.


Reproducible: Always


User Profile Reset: Yes



Additional Info:
I encountered this problem on different machines, on different Linux distros
and on Windows 10, using LibreOffice 6.2.7.1 (Windows 10, Ubuntu 16.04 LTS and
Xubuntu 18.04 LTS) and LibreOffice 6.3.0.4 on Manjaro 18.0.4.
