Internal server error

Hi, all.
I got error during installation of cryoSPARC on my new PC.
OS is centOS7, CUDAversion is 10.2.
The error messages are below.

I checked background process.
ps -ax |grep supervisord
And I confirmed the processes are not working.

I also have tried to restart cryoSPARC and reboot my PC.
But I got same error messages.

Do you have any ideas to solve this problem?
Thanks.

Sakura

I recently have the same error, did you figure out a solution?

Dear UNCuser

I could not solve this problem on new PC.
So, now I’m using cryoSPARC on another PC.
Best.
