2d classification display error after v4.6.2 update

Troubleshooting

Hi,
I’m getting an display related error after updating to v4.6.2 recently. The error is:

License is valid.

I’m connecting using this command: ssh -XY -N -f -L localhost:45000:localhost:45000 user@labserver

What’s strange is, I can open other remote displays like relion properly. I’m running CS live for motion correction and it’s running fine with all visualization options. Only 2D is giving weird things.

Also older CS used t work perfectly. Any advice ? or should I roll back !

Thanks

Setting aside security-related concerns regarding the -X and -Y options and doubts about combining the -X, -Y and -N options, I wonder whether password-less ssh access is properly set up and/or even needed on you CryoSPARC instance.

  1. Is this CryoSPARC installation intended to be and remain a single workstation/standalone-type CryoSPARC instance?
  2. What are the outputs of these commands:
    cryosparcm status | grep HOST
cryosparcm cli "get_scheduler_targets()"

Thanks for getting back.
Yes it is a single node server. This happened when I updated it from 4.4.1 to 4.6.2. My connection protocol and everything else remained the same.
I couldn’t figure out so I decided to roll back to 4.6 version and it’s working perfectly now.
