Unix connection refused

I have cryosparc V2 installed on a single work station and just updated it to the latest version. After update, I can’t see the webpage on port 39000 anymore.
When I tried to restart cryosparc, I got the following error.
Is there any problem with my setup?
Thanks,
Lei

$ cryosparcm restart
CryoSPARC is running.
