Hi.

Unfortunately there are issues that are beyond our immediate control. Here’s my previous post about it:

> However, for the time being the model download link won’t work. The new authentication link ([medcat.sites.er.kcl.ac.uk/auth-callback](http://medcat.sites.er.kcl.ac.uk/auth-callback)) needs to be registered manually. We’re working on this, but I’m not sure how long it will take exactly.

We have reached out to NIH regarding the change (a few weeks ago), but have not heard back. Given the uncertainties in the US public institutions, we’re not sure if there is anyone in the NIH that’s still willing/able/capable of resolving this issue.
