Issue
I did a new install and followed the tutorial for T20s. I keep getting the following error.

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.

Hi @sachint,

Can you ensure you have internet access on this machine?

Yes, I am connected to the internet.

[root@localhost Disk3]# ping activate.cryosparc.com

I did a fresh install but still get the same error.

Hi @sachint,

Are you running cryoSPARC behind an institution firewall? Sometimes these firewalls block HTTPS (encrypted) requested. To confirm, can you try:

curl https://get.cryosparc.com

You should see
{"message":"Missing Authentication Token"}

Any other response will mean that something is wrong, and you should see that there is an error, likely something to do with SSL.

You can work around this by adding the following line to your config.sh in the cryosparc2_master installation directory:
export CRYOSPARC_INSECURE=true

Let us know if that works.
