Error with license server; cryosparc v2.8.0; worker nodes not shown

Troubleshooting

Hi,
I am getting this error when trying to import micrographs from relion into cryosparcv2.8:

Error connecting to cryoSPARC license server. Checking local license file. Could not find local license file. Please re-establish your connection to the license servers.

Is it a transient issue with the server? If not how and where could one check the local license file?
Additionally, can the master be added as a worker in the same way as other workers are added? I have tried doing that but then during the execution of the job it does not show the different worker nodes and just shows:
Lane default (node) (node)

Thanks in advance,
Arka

Hi @arka,

Do these issues still persist? You may try restarting cryosparc: cryosparcm restart
Also, if you’d like the same machine you use as the master node to be used as a worker, see how to install a Standalone worker here:
https://cryosparc.com/docs/reference/install/#installation-standalone-worker
Just make sure that <worker_hostname> and <master_hostname> are the same.
