Frequent authentication issue: RemoteDisconnected #92
Description
The following error comes up very frequently (I think it is every time a new token is freshly issued):
(this issue has existed for some months now....)
e.g.
mc = ModelCatalog(HBP_USERNAME)
model_data = mc.get_model(.......) <- ERROR
The error disappears on re-running the same cell without any changes.
Error:
