Trying to preview app on iOS, and once it builds, it opens Xcode. I click the play button to open the emulator, and once it runs, I get a “Fuse not running” message, with an image of two kids arguing. Two more links on the bottom, change IP and try again. Fuse is running, so dont know what is causing it. ---

Do you have the local preview of that particular project running in Studio? Have you tried to run `fuse kill-all`, followed by `uno clean` in the project folder, and starting fresh again? ---

Is the device you’re previewing on connected to the same [wifi] network as the computer? Could it be that the network has a very restrictive firewall policy that doesn’t allow its clients to connect to one another? ---

Another question on top of that. When I do app preview in Appcelerator, it starts the iOS emulator and runs the app. When I do app preview in Fuse, it starts XCode, and then I have to click compile for it to run the emulator. Am I doing something wrong? ---

Can you please run `ifconfig` to check your public IPs, and then check which IPs are listed in the connection failure screen? Just to rule out that Fuse is detecting the wrong IP or something like that. You could also try to do `telnet 12124` in a terminal, to verify that Fuse is listening for connections. If you get “Connection refused” there is a problem. If you get a connection, Fuse is accepting connections, and you can just press Enter to return to the terminal. Furthermore, do you have a physical iOS or Android device you could try to run preview on, just to check if the problem is universal or limited to the iOS emulator? ---

So I cannot telnet to 127.0.0.1:12124 or 10.0.0.35:12124 I dont see the error screen on the app any more after I did Uno clean. So now that we know Fuse is not listening to connections, how do we resolve it? Btw, I do have an iOS and Android device I can test on. ---

When you’ve just verified that local preview is running, but you cannot telnet to Fuse, please check the following: - Do you have the Fuse icon in the macOS status menu? - What’s the output of `ps -ef |grep -i fuse`? There should be a process `/Applications/Fuse.app/Contents/MacOS/Fuse daemon` in that list. - What’s the output of `sudo lsof -PiTCP -sTCP:LISTEN`? There should be a process `Fuse` there, saying `*:12124 (LISTEN)` ---

Thanks for all the details! It looks like the Fuse daemon is indeed running and listening on port 12124 as it should, but it’s strange that you can telnet to it, and that the status menu icon isn’t showing. Just to rule out a few other things: - Does the example you’re trying to use work in local preview? - Have you tried to just launch Fuse, create an empty app (“New Fuse project” in the dashboard) and see if that works in local and iOS preview? If none of that works either, could you please try to run `fuse kill-all` followed by `fuse daemon` and paste the output of those commands too? ---

Status menu was showing, but I think it got lost after the 1.0 update?!? The iOS preview was never working, since 0.3 since I first installed it. On the observation side, Arduino is observing on localhost, while fuse seems to be on \*. Now, I made a new lank project, and: 1. Local preview works (displays blank white page) 2. iOS preview does not work (times out to connecting) After the commands, I got: ```auto Running at 127.0.0.1 port 12122 Client connected: Proxy Client connected: Sublime Text 3 Client connected: Code Assistance Service Client connected: Fuse Tray ``` The iOS preview failed, but I think it’s cause its now on 12122 and not on 12124. I can see the status bar icon now. Ideas? ---

Did another test, just to check if iOS emulator is communicating with the PC. I ran a simple python webserver on port 8000 serving an index.html file that only says “it works” when you load it. So I opened safari, pointed it to localhost:8000 and it loads the page. So emulator is talking to the pc on localhost. It also works on the WiFI IP.
