@systemaddict I would check the app's configuration. Some apps let you change the CORS. It's not correct for system adminsto change CORS settings, this is a security issue waiting to happen.
@ashkaptsov So, AppGyver's browser UI is going to make requests from the browser to n8n and baserow ? Can you tell us a bit more as to why would it want to do that? In general, adding CORS headers without knowing the app knowing about is a security hole.
