Following the tutorial, I have downloaded the test files and tried to import the movies and gain reference into workspace. And it shows: Unable to queue P1 J1: ServerError: Scheduler error: no scheduler lanes found. Please connect a worker using ‘cryosparcw connect’.
Welcome to the forum @799040451
Please provide additional details about this CryoSPARC installation, such as commands that were executed during installation and potential error messages.
In case this CryoSPARC installation was intended as a “single workstation”, part of the installation may have failed and cryosparcw connect may have to be run manually.

Now I installed it as master node only, and it shows again. I try to use cryosparcw connect
with these commands:
./bin/cryosparcw connect --worker u2256963
–master Yu-Latitude-5520
–port 39000\
But it shows like this:
CRYOSPARC CONNECT --------------------------------------------
Attempting to register worker u2256963 to command Yu-Latitude-5520:39002
Connecting as unix user u2256963
Will register using ssh string: u2256963@u2256963
If this is incorrect, you should re-run this command with the flag --sshstr

Please can you ensure CryoSPARC is runnig, then log on to
u2256963@u2256963,
copy the output of the command
curl Yu-Latitude-5520:39002
and post it to the forum.
Please also post the output of
cat /home/u2256963/cryosparc_user/cryosparc/cryosparc_worker/versioncat /full/path/to/cryosparc_master/version
Did this problem solved? If yes, can you provide your input. I am also getting the same problem.

Problem Solved. reinstalled cryosparc
Hi,
I met with the same problem. I followed the install instruction of single workstation. Here is the output of these three commands:
jk4882@icrc4lcga001:/mnt/data/cryosparc_worker$ /mnt/data/cryosparc_master/bin/cryosparcm status | grep -v LICENSE

I also notice that I cannot connect to CryoSPARC with localhost:39000 and icrc4lcga001:39000, but can connect with IP: like 10.115.231.55:39000
Thank for your time and help!
