Failed to save configuration: Error Domain=NEVPNErrorDomain Code=5 "IPC failed"

[ApplantaDev]

When I try to run the app, I get the following error:

Failed to save configuration: Error Domain=NEVPNErrorDomain Code=5 "IPC failed" UserInfo={NSLocalizedDescription=IPC failed}
Error Domain=NEVPNErrorDomain Code=5 "IPC failed" UserInfo={NSLocalizedDescription=IPC failed}
Go!
Error Domain=NEVPNErrorDomain Code=1 "(null)"

Do I have to request entitlements from apple?

Oh yes, there are 2 things about NetworkExtension: you cannot run on simulator, and you need entitlements even you just debug on your iPhone without releasing.

BTW this project is unfinished and I'm kinda abandoned it because of my procrastination -_-||| . I will finish this (with an elaborate installation guide) if you really need it :)

[ApplantaDev]

Thanks for the info. I was able to get the entitlements set up. Did you ever establish a VPN connection using the current code that you have now?

[davlxd]

Yes, I just complete this repo, and it works fine on my iPhone, with server side setup.

[ApplantaDev]

I just followed the instructions from both repos. I am still getting this as thew output in the console

VPN Status changed:
Invliad
VPN Status changed:
Disconnected...
Save successfully

VPN status is always invalid

My bad, my instructions are not elaborate enough. Here it is.

• After build & run simple-vpn-demo, your terminal should be like this.
• After build & run NEPacketTunnelVPNDemo on your iPhone, Xcode log window should look like this, iPhone screen should look like this. And this is where you are.
• The Connect at the center of iPhone screen is a BUTTON, after you click it, your iPhone screen should look like this, and Xcode log window should look like this. simple-vpn-demo terminal window should look like this, which means VPN server is now receiving traffic.
• Your IP address of http://whatismyipaddress.com/ on your iPhone should be different before and after click the Connect button.

Q.E.D.

Hi Touchcore, does this work for you? I am closing this issue if it does.

[ApplantaDev]

I will try this today and get back to you. Thanks a lot!

[ApplantaDev]

I got it working. However, the following method is never called in PacketTunnelProvider.swift:
startTunnel(options: [String : NSObject]?, completionHandler: @escaping (Error?) -> Void)
Do you have any idea?

[davlxd]

To verify it's called, you might need to set a break point and debug after Xcode attach to NEPacketTunnelVPNDemoTunnel, like this, kind of cumbersome.

[ApplantaDev]

For some reason I can establish a vpn connection but no methods in the PacketTunnel Provider file are ever called. This is my stackoverflow link http://stackoverflow.com/questions/42701530/packettunnelprovider-network-extension-not-called-swift-3

@visionstech were you able to overcome this Connecting-Disconnected problem?

[TheMrugraj]

Any update on this issue ?

Any update on this issue ?

Hi Sir, Do you able to solve the Connecting-Disconnected problem?

[TheMrugraj]

Yes, In my case I was missing an additional Capability for Personal VPN to add in entitlements.
