[Bug]: Raycast and VS Code extensions can't connect since v5.11.0 #967
Description
Activity
Thanks for the report! This isn't a problem with your port or settings. In v5.11.0 we tightened the security of the local API: most endpoints now require authorization. When we did that, we completely forgot about the external extensions. The Raycast and VS Code extensions don't send any token, so the app rejects their requests, and the extensions show the generic "app is not running or port is not correct" message.
The "Enable API integrations" option doesn't help yet either. For now the integration token is accepted only by the clipper and MCP endpoints, not by the endpoints the extensions use.
We'll fix this in the app and update both extensions so they work with the integration token, the same way the web clipper does. Until then, the Raycast and VS Code extensions won't work with v5.11.0 and later. Sorry for the inconvenience!
