ChatGPT in Xcode - Networking error

In the Coding Intelligence feature introduced in Xcode 26, when I send a message using ChatGPT in Xcode, the message “Your request couldn't be completed. Networking error.” appears and I’m unable to use the feature.

I suspect the issue may be related to the VPN or network proxy connected to my Mac and am attempting to investigate.

However, Xcode does not display any specific error details, nor does it provide a way to view them, which makes a detailed investigation difficult.

Next to the error message, there is a feedback button rather than a stethoscope (🩺) button, and the feedback window does not provide access to the underlying error information.

Is there a way to view the detailed network error logs generated by ChatGPT in Xcode? (I am using Xcode 26.0.1.)

Hmmm, I would expect the error message in the transcript to have a little arrow to expand to see the full, underlying error. If you aren't seeing that, please file a feedback request with a screenshot (or post the screenshot here) so we can take a look.

Otherwise, you could run this in the Terminal:

log stream --debug --predicate '(subsystem == "com.apple.IDEIntelligenceChat")'

Then reproduce, then attach that to the feedback request. And post the FB number here so we can take a look.

Thanks!

After running the log stream command, it was determined that the error was an SSL error caused by a self-signed certificate, and the problem was resolved. The attached screenshot shows the actual error that was occurring. Thank you for your help.
