hello, I install bitcoin-core from npm for my app to access my umbrel bitcoin rpc api but receive an 403 error status. I white list bitcoin-core to see if it is a problem of umbrel app-auth or app-proxy (.env.app\_proxy) but same result.  
Did some one can help me do call external call ot my umbrel (server side and client side (ajax))?
