CondaHTTPError when installing 3dflex

I’m trying to install 3dflex using the command bin/cryosparcw install-3dflex in the cryosparc_worker on the internet connected head-node, but get an HTTP error:

bin/cryosparcw install-3dflex
Installing 3D Flex Refine dependencies...

HTTP errors are often intermittent, and a simple retry will get you on your way.
