inference.opencode.ai returns NXDOMAIN - App stuck on "Thinking" forever (Windows) #15753

Description

Bug Report

Description

OpenCode Desktop is stuck on "Thinking" forever when sending any prompt. The app loads normally, I can select a model, but after submitting a prompt it never gets a response.

Root Cause Found

After investigation, I found that inference.opencode.ai (the API endpoint the app uses) cannot be resolved by any DNS server — including Google (8.8.8.8) and Cloudflare (1.1.1.1).

Proof:
nslookup inference.opencode.ai 8.8.8.8
Server: dns.google
Address: 8.8.8.8
*** dns.google can't find inference.opencode.ai: Non-existent domain

This means the domain either does not exist or has been misconfigured on OpenCode's infrastructure side.

Environment

• OS: Windows 11
• OpenCode version: Latest (freshly reinstalled)
• Network: Home WiFi (ISP: Turkey)

Steps to Reproduce

1. Open OpenCode Desktop
2. Select any AI model (e.g. MiniMax M2.5)
3. Type any prompt and submit
4. App hangs on "Thinking" indefinitely

What I Tried

• Reinstalled OpenCode multiple times
• Flushed DNS cache (ipconfig /flushdns)
• Changed DNS to 8.8.8.8 and 1.1.1.1
• Added firewall exceptions for OpenCode.exe
• Tested on mobile hotspot — works fine (likely due to cached DNS)

Expected Behavior

inference.opencode.ai should resolve correctly and the app should return AI responses normally.

Additional Notes

This issue started recently and may be related to a recent infrastructure or DNS change on OpenCode's end.
