n8n - 💡(How to fix) Fix "Connection lost" message in each workflow [2 comments, 3 participants]

Describe the problem/error/question

For quite some time I experience "Connection lost" messages when I'm logged in n8n.

What is the error message (if any)?

"Connection lost" Browser log: Connection lost, code=1005 [WebSocketClient] Attempting to reconnect in 1000ms ... Loading the script 'data:text/javascript,if(!import.meta.resolve)throw Error("import.meta.resolve not supported")' violates the following Content Security Policy directive: "script-src-elem 'self' 'unsafe-inline' blob: https://cdn-rs.n8n.io https://ph.n8n.io https://us.i.posthog.com https://us-assets.i.posthog.com https://cdn.jsdelivr.net https://cdn.tailwindcss.com". The action has been blocked.
