Another program is already listening on a port

Troubleshooting
1

Hi folks,

I am new to cryosparc (just installed it). I typed “cryospac start” a few times with the hope to see the dashboard (which I do not see) and now getting the error below.

Do you know how to fix this?

Many thanks!
Elena

cryosparc start
Starting cryoSPARC…
Error: Another program is already listening on a port that one of our HTTP servers is configured to use. Shut this program down first before starting supervisord.
For help, use /home/exx/cryosparc/anaconda2/bin/supervisord -h

Hi @zehre
Can you please try

ps -ax | grep supervisord

This will list any supervisor processes running potentially from a previous failed attempt to start cryosparc. All of them need to be killed via

kill PID

The PID comes from the output of the previous command. Once done, you can

cryosparc start

Please let us know if this works. Thanks!

We had the same problem. This solution worked perfectly for us.
