User not found and app stopped after hostname change

I changed the hostname for one of the users at our HPC by referring to the Migration Guide. The instance is accessible via the browser on the the new host name but it says user not found. How should I proceed?

  • Should I create a new user account and migrate the previous projects and jobs?
  • Is there a way to retrieve the previous user account?
  • Why is the app_api_dev, app_legacy and app_legacy_dev still showing up as STOPPED?

CryoSPARC version is v4.1.2

Output of commands:

  • cryosparcm listusers

Can anyone suggest what could be going wrong?


The empty users list is consistent with a “fresh” CryoSPARC database. A fresh database could have been created during CryoSPARC startup if the CRYOSPARC_DB_PATH variable inside cryosparc_master/ does not point to the correct database directory.
What is the output oft he command

cryosparcm status | grep -v LICENSE_ID


What did this change entail:

  • reinstallation of the software?
  • a hostname change without changes of underlying storage or software installation?

Is this topic related to Database EXITED after accessing projects in the GUI. Does it concern the same CryoSPARC installation?
