Connection Failed on macOS with both Automatic1111 and ComfyUI #84

Description

@NatCosmos

Hello, I'm having a persistent connection issue on my MacBook.

System:

  • OS: macOS Sequoia 15.5
  • Photoshop: Adobe Photoshop 2025

Problem:
The plugin fails to connect to any local server. I have tried two different backends:

  1. Automatic1111: The server is running correctly with the --api flag and works perfectly in the browser at http://127.0.0.1:7860. The plugin gives a "Automatic1111 is Offline" error.

  2. ComfyUI (Desktop version): The server is running correctly and works perfectly at http://127.0.0.1:8188. The plugin gives an "Unable to establish a connection to ComfyUI" error.

What I've already checked:

  • The servers are 100% working.
  • macOS built-in firewall is configured to allow connections for Photoshop and Python, and the issue persists even when it's completely turned off.
  • I have no third-party antivirus or firewall software installed.

The problem seems to be with the plugin's ability to make a localhost connection from Photoshop on my system. Could you please help? Thank you.
