Cannot open user interface

Install, Configure and Update
1

I successfully installed CryoSPARC in May of this year and had already submitted jobs through the user interface, which ran without issues. However, a few months later, when I tried to start CryoSPARC again using cryosparcm start, I was unable to access http://localhost:39000/ due to a connection timeout. Could you please advise on what might be causing this? Could it be related to not updating the software? I am currently attempting to update to the latest version.

Welcome to the forum @AnnieYuan . Please can you

  1. confirm whether your web browser where you entered the http://localhost:39000/ is running on the CryoSPARC master computer or on another computer.
  2. post the outputs of the commands (on the CryoSPARC master server):
    cryosparcm status
ps -eo user:12,pid,ppid,start,cmd | grep -e cryosparc_ -e mongo
ls -l /tmp/mongo*.sock /tmp/cryosparc*.sock
cryosparcm call env | grep -i proxy
curl 127.0.0.1:39000
host localhost

  1. the web browser is running on the CryoSPARC master computer.

  2. here are the outputs.

localhost has IPv6 address ::1

Thanks for posting the information.
The computer’s hostname and the network configuration may work for a single workstation-type CryoSPARC installation, but would not be suitable if you wished to add additional CryoSPARC worker nodes in the future.
Are you able to access the UI from a browser on the CryoSPARC master computer using the URL http://127.0.0.1:39000?

Thank you for the reminder.

The URL still cannot be opened.

If the URL cannot be opened in the browser that’s running on the same computer as the successful curl 127.0.0.1:39000 command earlier, I wonder whether the browser ran with different proxy settings than the curl command. What command do you use to open the browser? If you opened the browser by pushing a button, the command may be found by inspecting the browser/button settings.
