Raw exception messages ("Access is denied", HttpRequestException
stack traces) gave the user nothing to do. The flow now translates
the common failures into plain language and offers a one-click
retry that re-runs the host/join flow from the top:
- ErrorTranslator handles HttpRequestException (network down),
TaskCanceledException (timeout), SocketException (firewall),
UnauthorizedAccessException + IOException "in use" (Rec Room
open), missing folder / files (re-pick install), cloudflared
download truncation (suggests LAN mode), port 5005 already bound
- Patcher log output goes through TranslateMessage which catches
the same "access denied" / missing files cases
- HostStepsPanel / JoinStepsPanel gain a Retry + "Get help" row
below the steps; visible only on failure
- "Get help" opens README.md#troubleshooting on GitHub
- Stop / new run hides the retry row so a fresh start is clean
