Swing wallet Zcash daemon


Hello, I am not able to download the blockchain, I try several times and at all times I have an error message "An unexpected error occured when updating the GUI wallet state. Please ensure that the ZCash daemon is running.
Error time from wallet: error: could not connect to server: timeout reached (code 0) (make sure that you are connecting to the correct RPC port)
Would you have a solution?
