CryoSPARC process error related to DISPLAY?


I was running cryoSPARC version: v2.9.0 fine on a linux/Centos system until I changed the DISPLAY parameter (in the process of installing another program).

Now, when I try to run the cryosparcm status command, I get the following error and can’t connect to cryoSPARC:
unix:///tmp/cryosparc-supervisor-19926dcc439c23d73ac259ba81582779.sock refused connection

details are pasted below. Please help!

[cryosparc_user@c103454 etc]$ cryosparcm status

CryoSPARC System master node installed at/home/cryosparc_user/software/cryosparc/cryosparc2_master
Current cryoSPARC version: v2.9.0


cryosparcm process status:

**unix:///tmp/cryosparc-supervisor-19926dcc439c23d73ac259ba81582779.sock refused connection**
