3.12 issue? dashboard not loading on 127.0.0.1

some users updating to 3.12 are seeing their agent fail with an anthropic error and the dashboard showing “127.0.0.1 refused to connect.”

that message simply means the openclaw gateway is not running, so the browser has nothing to connect to.

try this real quick if this is you:

1. open terminal / command prompt

2. start the gateway

openclaw gateway start

1. wait ~10 seconds

2. refresh the dashboard page.

if it still fails, check logs:

openclaw logs

if you see an anthropic initialization error, it may be the 3.12 regression some users are reporting.

temporary fix that’s working for people:

npm install -g openclaw@2026.3.11
openclaw gateway start

if the dashboard loads after rolling back, the issue was likely introduced in 3.12
