Welcome to our forum, @treeves. Even though some users have managed to connect via redirectors, it is not due to updates on our end since we have yet to delve further into diversifying our proxy connection options. As I mentioned above, in spite of the details kindly provided by users like @zhao.paperpile, we have been unable to properly troubleshoot since we lack test access to OpenAthens servers (if any university/institution is able to share one, we would be most grateful), so there is little we can do from our end until we are able to actually develop the feature.
At the moment our resources are entirely dedicated to getting our new extension and web app (currently in beta) released to the public. Once that’s up and running, we will be able to shift focus back to this and other topics.
