@m4nii Thanks for updating

KevinTheJedi I have done several scenarios and uploaded screen captures of the events.

  1. Add message first.
  2. Upload files from “Choose Files”.
  3. Do not wait for “all changes save”

Outcome 1: Erratic
a. First case all files missing
b. Second case all files uploaded successfully.

  1. Upload files from “Choose Files”.
  2. Add a message, wait for draft to save,
  3. then click send

Outcome 2: Erratic
a. At times, not all attachments appear in thread

  1. Add message first.
  2. Upload files via “Drag n Drop”.
  3. Either wait for “all changes save” or “ unsaved”

Outcome 3: Normal
a. All attachments appear in thread

The problem is not occurring when using “Drag n Drop” feature for attachment.

Scenario 4:

  1. Add message first
  2. Wait for ‘all changes save’
  3. Attach documents individually or multiple selections from browse

Outcome 4: Normal
a. All attachments saved and appear in thread.

@m4nii can you try using drag n drop method only and check if you get any missing attachments.

*If the video links are dead, let me know I will re-upload.

    For info, I am using Windows 10 PC and doing the tests on Microsoft Edge Version 112.0.1722.39 and Chrome Version 112.0.5615.87. Those are the latest versions available.

      Have you have the time to check if you get upload issues when using only the Drag and Drop feature?

          a month later

          Unfortunately, we also have this problem again and again with some of our employees. With some there are no problems, some report that either all file attachments are missing or only individual ones after the reply has been sent. Very annoying.

          (all using Windows with the latest Chromium Edge)

          visham At least for us, the method of uploading an attachment doesn't matter. The problem occurs randomly and not for everyone. However, all employees use the same programs (current Windows 10 with current Chromium Edge) and current osTicket 1.17.3

          There are no errors in the error log from the server, as with the others above.

            5 months later

            Experiencing the same issue as the others above. We are running v1.18 and have intermittent reports of attachments that appear to upload during a reply, but once you save/send, they are gone! Vanished. Like the upload never happened. (All agents are up-to-date Chrome. Server is current PHP 8.x Linux.) No sign as to WHY this happens here. It just DOES, and only once in a while, and this seems to plague certain random users more than others. No clue why its happening, but we've been running for about a month successfully, and now this just started. (It's quickly eroding trust in this system.) If we cannot trust the system, people will not continue to use it. Our agents are asking us to fix it ASAP or consider switching systems. (We have a provider/customer relationship with these users, so if we can't make this work 100%, we'll need to shop for a new ticketing solution. This is NOT good.)

            Is there ANY clue as to why this continues to happen? (Clearly it's a wider-spread problem, as other osTicket installs are experiencing the same problem, and this particular issue has been reports since like v1.2 that I'm aware of, so it's YEARS old.)

            I'd appreciate any help or insights, since as newer osTicket adopters (but a month in with nearly 1,000 tickets) we aren't sure how to proceed with these problems persisting.

            Any thoughts/resolution at all???

              You need to find a replicable case and see how exactly they are uploading, what they are uploading, etc.; essentially exact steps to replicate. You can also look at the Network tab in the browser's developer tools for the failed request and see what error it gives you. You should also have the people who can replicate try on a new browser with no browser extensions, etc. as the extensions can sometimes cause issues as well. You should also ensure you don’t have "Bind Agent Session to IP" setting enabled as this can sometimes cause session issues. You should also try increasing the Agent and User session timeouts in the system settings.

              Cheers.

                Thanks Kevin!

                I've disabled the Agent and User timeouts. (We actually have no users that aren't agents. Everything on the front-end is pretty much dead/disabled. We do email-only support.)

                Unfortunately, it's not something I can easily reproduce. These are end-users in other locations reporting stuff after-the-fact. It's all completely intermittent, and honestly only happens rarely - I haven't seen it happen in person, but it happened today with a single user 3 or 4 times in a row, and that pretty much panicked everyone. (This is a trusted, competent user here, so we know what they are telling us is true.)

                The human challenge here is that, "This doesn't happen with other systems." So these users are experiencing a failure that they DO NOT experience with any of the other systems they use daily.

                I don't know what to say. I hope this session timeout thing fixes it. (And if it does, you should probably look into why it's happening with limited session timeouts...definitely a software issue in that case!)

                A thought/note: We previously had a different timeout for User sessions than Agent sessions. The Agent timeout was longer. Could something regarding attachments be related to the user timeout? Like the Agent still has the session, but the attachment is tied to User timeout, so it fails??? (I say this, because when I tried to "close" the front-end by limiting User/front-end portal to only a certain IP through Settings, it did indeed BREAK attachments for Agents on the backend trying to download...they could not access the attachment URLs because the front-end was blocking their IP.)

                It does seem that the system has at least that know issue, where agents should have been able to access attachments regardless of the front-end being "locked".

                I hope this helps...

                  That’s because all file URLs point to the files.php file. You should’ve added an exception for this file for attachments to work for Agents.

                  User sessions are only tied to Users and are completely separate from Agents.

                  We have reports of session issues which we are actively looking into.

                  Cheers.

                      Thanks for the heads-up on needing an exception for the files.php when blocking the front-end by limiting IPs. Look forward to hearing a solution on the session issues, which hopefully resolves the problem with file attachments occasionally just getting "lost" when replying to tickets. (EDIT: Adding, "In the meantime, I've just disabled session timeout - set to 0 - to see if that resolves it, at least temporarily.")

                        Have you had any more errors after configuring session timeout to 0? I have also been getting reports of this issue happening randomly.

                          a month later

                          KevinTheJedi Wanted to let you know that I configured agent session timeout to 0 on 18.12.2023 and since then no errors have been reported to me.

                            17 days later

                            FYI, we are experiencing this too.
                            Attempting the Agent Session Timeout = 0 now, it was previously set to 43830.
                            We have multiple agents having this, its intermittent, we use firefox,

                            osTicket Version 1.18-git

                            MySQL Version 10.6.16
                            PHP Version 8.2.15

                              I would recommend three things:

                              1. Make sure you are using the latest, officially packaged version of osTicket from our website.
                              2. Make sure you have the latest Filesystem plugin installed.
                              3. Check your PHP and webserver settings to ensure your max post size, etc. are adequate enough.

                              Cheers.

                                  PHP settings are good, we have been using OSTicket for years no problem.
                                  We do have our own mod's in it but nothing major.
                                  Just checked we have the latest branch merged on git.
                                  At best estimate we think it might have started around about the time we merged in
                                  https://github.com/osTicket/osTicket/commit/3dd2ed35f3bfd2f061f46395b5a863b40c3f97a9
                                  or
                                  https://github.com/osTicket/osTicket/commit/4689926b2d3d25754f0ddcf8d4e181a2817f6d56

                                  Hopefully this helps, i'll test the agent sessions = 0 and see if we have more issues, but might take me a week to say either way

                                      Well none of those commits relate to attachments so those are not it. Unless you mean when you merged up to those commits.

                                      Cheers.
