Failed to remove browser container

Error message

Failed to remove browser container

What it means

Cleanup failure in stopSession: `docker rm -f <container>` exited non-zero and stderr does not match 'no such container' (which is treated as already-gone success). Means the container could not be removed — Docker daemon issues, a wedged container, or timeout at 20s. The session was already deleted from SESSIONS, so this leaves a potential orphaned container for reconcileStaleContainers to collect later.

Solutions

1. Retry docker rm -f manually or restart the session stop
2. Run docker ps -a to find the orphaned container and remove it
3. Rely on reconcileStaleContainers to sweep leftovers on the next session start
4. Investigate Docker daemon health if removals persistently fail
