Using version 8.1.26 Android devices and browser works. IOS **app** gets a 55kb empty file. This happens with jpg, pdf and text files. IOS device can download file using browser without issue. The download does get the correct filename. I uses the command "system.perspective.download(filename=filename, data=filedata)" ---

I would report to support, I've come across bugs in the perspective app when downloading in the past. If it works on browser and android fine, it's likely a bug in the iOS version ---

Try specifying a Mime type. Here's an example of an onClick action where an image file is in the gateway's data folder. Edit: I've also filed a ticket to look into making this a bit better. ````auto from java.io import File from com.inductiveautomation.ignition.gateway.util import MimeTypeUtils fileName = 'data/image.png' target = File(fileName) if (target.exists()): data = system.file.readFileAsBytes(fileName) fileName = target.getName() contentType = MimeTypeUtils.determineMimeType(fileName) system.perspective.download(filename = fileName, data = data, contentType = contentType)``` ```` ---

We are using an iPhone with version 16.5 of ios. We have added the mime type specification, but that does not fix the issue. It still only gives up a 55 byte file. This is the same whether we are exporting a pdf/png/jpeg These all work with Android phones. ---

We just tried the sample project in the application. The download button on the page 'Database Management \> Document Management' does work on the iPhone. So there is something different going on there. I will download the Perspective Document Management project and see what is different in there. ---

Have a little bit more information. It looks the 55 byte file is actually a text string: \Bad Message 400\\reason: Bad HostPort\ I was trying to troubleshoot the app by viewing the log file but iOS logfile i just a line saying "Unable to create a temporary copy of log file." ---

Hey @paull, What is your gateway's webserver configuration? Do you have force secure redirect and the Public Address Setting `Auto Detect HTTP Address` enabled/disabled? It looks like its an issue specifically within the gateway but im not 100% sure yet ---

I have force secure redirect and Auto Detect HTTP Address enabled. I am using port 443. This is set up on a AWS instance. It is version 8.26. ---

Still working through this issue. Watching the log and everytime the iOS device goes to download, there is a Websocket connection errored out log. ```auto java.nio.channels.ClosedChannelException: null at org.eclipse.jetty.websocket.core.internal.WebSocketSessionState.onEof(WebSocketSessionState.java:169) at org.eclipse.jetty.websocket.core.internal.WebSocketCoreSession.onEof(WebSocketCoreSession.java:253) at org.eclipse.jetty.websocket.core.internal.WebSocketConnection.fillAndParse(WebSocketConnection.java:482) at org.eclipse.jetty.websocket.core.internal.WebSocketConnection.onFillable(WebSocketConnection.java:340) at org.eclipse.jetty.io.AbstractConnection$ReadCallback.succeeded(AbstractConnection.java:314) at org.eclipse.jetty.io.FillInterest.fillable(FillInterest.java:100) at org.eclipse.jetty.io.ssl.SslConnection$DecryptedEndPoint.onFillable(SslConnection.java:558) at org.eclipse.jetty.io.ssl.SslConnection.onFillable(SslConnection.java:379) at org.eclipse.jetty.io.ssl.SslConnection$2.succeeded(SslConnection.java:146) at org.eclipse.jetty.io.FillInterest.fillable(FillInterest.java:100) at org.eclipse.jetty.io.SelectableChannelEndPoint$1.run(SelectableChannelEndPoint.java:53) at org.eclipse.jetty.util.thread.strategy.AdaptiveExecutionStrategy.runTask(AdaptiveExecutionStrategy.java:416) at org.eclipse.jetty.util.thread.strategy.AdaptiveExecutionStrategy.consumeTask(AdaptiveExecutionStrategy.java:385) at org.eclipse.jetty.util.thread.strategy.AdaptiveExecutionStrategy.tryProduce(AdaptiveExecutionStrategy.java:272) at org.eclipse.jetty.util.thread.strategy.AdaptiveExecutionStrategy.lambda$new$0(AdaptiveExecutionStrategy.java:140) at org.eclipse.jetty.util.thread.ReservedThreadExecutor$ReservedThread.run(ReservedThreadExecutor.java:411) at org.eclipse.jetty.util.thread.QueuedThreadPool.runJob(QueuedThreadPool.java:934) at org.eclipse.jetty.util.thread.QueuedThreadPool$Runner.run(QueuedThreadPool.java:1078) at java.base/java.lang.Thread.run(Unknown Source) ``` ---

I was able to reproduce this locally and have opened a ticket to address this. Im targeting the next release of the mobile app, no ETA on when that will come out, but ill be working on a basket of tickets for that release after my current work.
