iOS Question B4i Simulator debugging no longer connects to IDE

[marcick]

Hi,
I'm having a strange issue with B4i simulator debugging that never happened before.

My setup has always worked fine for years:

• Windows PC with B4i IDE
• Mac on same LAN running B4i Build Server
• Xcode + iPhone Simulator

I hadn't used the Mac for about 2 months. Today I powered it on again and now I have this problem.

Honestly, I have the feeling that I'm simply forgetting something stupid or obvious, but I can't figure out what.

Current behavior:

• Build succeeds correctly
• App gets installed and launched in iPhone Simulator
• Then immediately I get the white screen saying:

"No WiFi connection! Waiting for IDE to connect"

What I already checked:

• Build Server works correctly (compilation succeeds)
• Windows ↔ Mac connectivity OK
• Ping works both directions
• Firewall disabled on Mac
• Network is Private on Windows
• Simulator reset / erased
• Restarted Mac, Windows, Xcode, Simulator, Build Server
• Cleaned project / Objects folder
• Ports reachable from Windows to Mac

Interesting detail:
On the Mac, while the app is running, these ports are listening:

58192
58193
58194

(using lsof -nP -iTCP -sTCP:LISTEN)

and they belong to my app process.

But on Windows, B4i.exe sometimes tries connecting to different ports like:

192.168.1.57:58191
or
192.168.1.57:58196

and the connection stays in SYN_SENT.

It looks like the simulator/debugger ports and the IDE are somehow out of sync.

I did NOT change:

• B4i version
• Build Server version
• Project
• LAN configuration

The only thing that changed is that the Mac had been powered off for a couple of months.

Any idea what could cause the simulator debugger handshake to fail like this?

Thanks!

Are you able to run the app on a connected real device?
