A local proxy can stall tool startup before the model runs
By OnTheRice · Sources and limitations · Report a correction
A VS Code Insider report links a sandboxed tool-startup timeout to a proxy on the same Mac. Teams using that setup should check startup routing before changing models.
Source confidenceNot assessed
What’s changing?
The reporter’s controlled test worked with an explicit sandbox proxy route while direct local-host access stayed blocked. A separate startup fix does not establish that this route is repaired.
Key points
- A VS Code Insider report links a sandboxed tool-startup timeout to a proxy on the same Mac.
- Teams using that setup should check startup routing before changing models.
What could change this view?
- This is one reported Insider setup, not an OTR reproduction. The newer runtime has not been fully retested; other addresses are unverified.
Bottom line
Admins with this setup: inspect startup logs, proxy location and the sandbox route. Keep protections in place and test only an approved, narrow routing correction.
This is based on the information recorded with this signal.
How likely is this call? · Three frameworks

Sources, original wording and price checks
Original research record
The reporter’s macOS test stalled while a Playwright tool server started, before model dispatch. With both proxy variables set to 127.0.0.1, registry requests were denied before reaching the proxy.
The reporter’s controlled test worked with an explicit sandbox proxy route while direct local-host access stayed blocked. A separate startup fix does not establish that this route is repaired.
OTR’s view: this timeout calls for a routing check, rather than an assumption about model performance.
Admins with this setup: inspect startup logs, proxy location and the sandbox route. Keep protections in place and test only an approved, narrow routing correction.
This is one reported Insider setup, not an OTR reproduction. The newer runtime has not been fully retested; other addresses are unverified.
A matched test should start the tool through the intended route while retaining local-host restrictions.
A different reproduced cause or a current runtime that no longer fails would remove this diagnosis.
Check before the next affected startup test. No asset direction or trade entry.

What changed: The reporter’s macOS test stalled while a Playwright tool server started, before model dispatch. With both proxy variables set to 127.0.0.1, registry requests were denied before reaching the proxy.
Directional takeaway: UNASSIGNED / NO ENTRY
OTR reasoning: The reporter’s controlled test worked with an explicit sandbox proxy route while direct local-host access stayed blocked. A separate startup fix does not establish that this route is repaired.
Counterpoint: This is one reported Insider setup, not an OTR reproduction. The newer runtime has not been fully retested; other addresses are unverified.
