Could not find local license file



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.
When I opened the project and imported the data images but it is showing the above error. What should I do now.


Hi @AfsarKhan,

Can you please tell us the version of cryoSPARC you are running? Can you also confirm if the master node has internet access?

CryoSPARC System master node installed at
Current cryoSPARC version: v2.12.4

cryosparcm process status:

app                              STOPPED   Not started
app_dev                          STOPPED   Not started

webapp_dev                       STOPPED   Not started

We got this result.

And Internet is accessible to the system because we installed the cryoSPARC in standalone system.


Sir, We are still waiting for your response.
Please help us to sort out the problem.
Thank you


Hi @AfsarKhan,

If you log into the machine via ssh, and do


you should get a response that says:

{“message”:“Missing Authentication Token”}

This indicates that you are connected to the internet and can access our license servers. Any other output/error indicates something is wrong with the network.
