What's Wrong?

Your upgrade killed my work for some 6 hours today. Old 2.0.71 still connects and works. The new 2.0.72 I have been getting this shit all day:

Let me read the romaji syllable specification - that should explain the fundamentals I'm missing.

Confirming this issue on 2.0.72. Multiple sessions getting stuck with 'Request timed out. Check your internet connection and proxy settings' errors after tool calls succeed. Network connectivity tests show API is reachable (0.2s response time, DNS resolving correctly). The sessions are not frozen - they respond but every API call keeps failing with retry loops (attempt 7-8/10). Ctrl+C and /clear don't reliably recover the session. This is a recurring issue that significantly impacts productivity and trust in the tool.
