cryoSPARC license server

I faced this problem “Error connecting to cryoSPARC license server. Checking local license file. Could not find local license file. Please re-establish your connection to the license servers.”
I tried to do curl The respondense was curl: (6) Could not resolve host:
I also tried modifying the CRYOSPARC_INSECURE variable to be true and restart cryosparc . The problem still existed . So how to solve this problem? Even if i updated to cryosparc v3.2. It didn’t work.
