## TL;DR

Check your version of Browserless first , maintainers often fix the underlying bug in a later release, and the thread may predate it.

## Steps

1. Issue browserless/browserless#3023 (closed, 10 comments): After last Update , When press run button,on Search page getting : Couldn't establish a connection "ws://CONTAINER_IP:3007/". Is your browser running? Befor Working fine... using Unraid (Linux 64) Docker lasted version [image]

2. 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.

3. This comes from one real issue thread (https://github.com/browserless/browserless/issues/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.
