Thanks for posting. First of all, is this on our hosted Notebook service (nb.anaconda.cloud) ? and are you using the free tier of the service? Do you know what external domain the xbbg package is connecting to (e.g. bloomberg.net)?
The reason that I ask is that I’m thinking this may be due to the outbound allow lists that the service has in place. Basically, the external sites that free users can reach from the notebook service is limited to a known “safe” list. I’m thinking that the address for the Bloomberg Terminal is not in the allow list.
