What issue are you seeing?

Subject: Android remote access cannot connect to ChatGPT desktop on Windows
I cannot connect to my Windows ChatGPT/Codex desktop app from either Android phone through the ChatGPT mobile app.
Phone error:
“Failed to connect to ChatGPT desktop. Make sure the ChatGPT desktop app is open, then try again.”
Timeline:

• Remote access worked during a long session yesterday.
• It disconnected during that session and has not reconnected since.

Confirmed:

• The desktop app is open, updated, and signed in to the same ChatGPT account as both phones.
• Pairing succeeds, and the desktop app records the phone as recently connected, but the phone cannot load remote threads or establish an active connection.
• The issue occurs on two Android phones.
• The issue occurs over both Wi‑Fi and cellular data.
• I restarted the laptop, removed and re-created a phone pairing, and signed out and back in to the desktop app; none resolved it.
• No active Windows VPN was found.
• Windows Firewall has an enabled outbound Allow rule for ChatGPT.
• OpenAI’s status page showed no declared system-wide incident during testing.

Technical environment:

• Windows 10 Pro
• Current Codex/ChatGPT desktop app: OpenAI.Codex 26.818.3698.0
• ChatGPT Classic 1.2026.190.0 is also running on the laptop. It has not been closed because it is not known whether it is relevant.
