Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

Failed to connect to an IPC Port


Problem on UE 4.6

When I'm deploying to the iOS device the ipa file is built fine, but there is a problem with sending it to a device. Very often I'm receiving an error message:

 LogPlayLevel:Display: IPhonePackager: IPP ERROR: Failed to create deployment server process (File specified cannot be found.)
 LogPlayLevel:Display: IPhonePackager: IPP ERROR: Error while executing command: System.Runtime.Remoting.RemotingException: Failed to connect to an IPC Port: File specified cannot be found.

Usually it can be fixed by changing USB port, but on some computers it doesn't work.

Are there any clues what to do to fix/workaround this problem?

Any updates on this issue? I am having the same problem.

Having same problem. Have tried to launch game on iOS from Editor 2 times and twice it crashed with this error. :(

I'll try and help you get through this. Can we confirm that the IOS binaries arent still running in the background when this occurs? and that both of these binaries exist.

UE4/Engine/Binaries/DotNET/IOS/IPhonePackager.exe UE4/Engine/Binaries/DotNET/IOS/DeploymentServer.exe

Hi, Terence

I looked for UE4/Engine/Binaries/DotNET/IOS/DeploymentServer.exe and didn't find it. Actually it didn't build when I built UE4.sln. I built it manualy now and also Mobile Device Interface. After this manipulations my app finally launched from Editor! Thank you, but... ... it fails to launch (deploy step) from time to time. Anyway thank you a lot. With this I can live now =)

Yup, it was it! No DeploymentServer.exe. Like Creo said from time to time the deploy fail, but now it's better than it was :)

Terence.Burns pointed out that the UE4/Engine/Binaries/DotNET/IOS/DeploymentServer.exe is needed for deploy and the error shows usually when this file is missing.

Funny thing that it was missing somehow at first place, but this is good place to look. Thanks :)

Hey zompi2,

Do you happen to have itunes installed on those pcs where it is an issue?


avatar image zompi2 Jan 08 '15 at 06:10 PM

Yes. Without iTunes there is no option for building on iOS.
