unable to download models about celltypist

[prete]

Hi @mxiang1, thank you for using CellTypists.

Can you check if you can access the URL from a web broswer in the same network?
Paste this in your browser: https://celltypist.cog.sanger.ac.uk/models/models.json does it load properly?

From the same environment you can try to retrieve the model list using wget or curl.

wget -O models.json https://celltypist.cog.sanger.ac.uk/models/models.json

Does that work?

If some of those still don't work, then it may be an issue with the web proxy on your network that's blocking the URL.

Hi Prete,

​I tested the wget command and also failed to connect.

$ wget -O models.json https://celltypist.cog.sanger.ac.uk/models/models.json

Unable to establish SSL connection.

I'm connecting from our institutional HPC and the support team told me there seems to be a restriction put in place on the Sanger side which doesn't accept connections from Stanford systems.

The same is happening here.

Any attempt to download a model using the python API in our HPC fails due to connection timeout.

However, manual download from the browser in my personal laptop seems to work fine.
