📄 Description

Description

Adds troubleshooting documentation for Chrome 142+ blocking localhost connections to LangSmith Studio.

Problem

Starting with Chrome version 142, users are experiencing "Failed to initialize Studio" errors when trying to connect LangSmith Studio to their local development server via langgraph dev. This is due to Chrome's full enforcement of the Private Network Access (PNA) specification, which blocks HTTPS sites from accessing HTTP localhost servers by default.

Changes

  • Added new "Chrome Connection Issues" section to src/langsmith/troubleshooting-studio.mdx
  • Documented symptoms users will encounter
  • Provided step-by-step solution to allow local network access in Chrome settings
  • Added additional troubleshooting steps for browser extensions, dependency updates, and cache clearing

Testing

  • Verified markdown syntax is correct
  • Confirmed no linting errors
  • Tested that links and formatting render correctly
