An error ocurred while checking license status
Could not get license verification status. Are all CryoSPARC processes RUNNING?

$curl https://get.cryosparc.com/checklicenseexists/$LICENSE_ID
{"success": true}%

Please can you post the outputs of these commands

free -h
grep -v CRYOSPARC_LICENSE_ID /home/dongzhuoer/.local/cryosparc_master/config
ss -anp | grep ":414[0-9] " | sed 's/\s\+/ /g'
cryosparcm log supervisord | tail -n 30
cryosparcm log command_vis | tail -n 20

Thanks!
I found the problem lies in HTTP proxy.
After I removed export http_proxy=http://xxx.xxx.xxx.xxx:xxxx from the ~/.bashrc file, cryosparcm restart works well.

By the way, it still quite confusing that curl https://get.cryosparc.com/checklicenseexists/$LICENSE_ID succeed while cryosparcm status failed with license issue

Is curl defaulting to NO_PROXY (via alias or config file)?

curl -x http://xxx.xxx.xxx.xxx:xxxx https://get.cryosparc.com/checklicenseexists/$LICENSE_ID returns {"success": true}
