## What works
If the browserless WebGui suddenly can't connect after an update ('Couldn't establish a connection ... Is your browser running?'), check which image tag you're on. The reporter fixed it by switching to the browserless/chrome:1-chrome-stable tag, where the WebUI connection worked again. Worth trying the stable tag before digging into networking.
## Caveats
This comes from one real issue thread (gh:browserless/browserless#3023); it is the verified fix or approach from that thread, not a general manual. Check your version of Browserless first , maintainers often fix the underlying bug in a later release, and the thread may predate it.
