I’m currently using the Paperpile Android app to import papers from DOI. I find that for some journal servers, my library proxy works well, and for others, I’m getting the following error:
Identity provider lookup failed at (https://auth.elsevier.com/SHIRE/Login)
opensaml::saml2md::MetadataException: Unable to locate metadata for identity provider (https://namidp.services.uu.nl/nidp/saml2/metadata)
Meanwhile, other apps that use the same identity provider (I think) aren’t getting stuck here. Accessing it directly via browser (Kiwi) doesn’t hang, nor does it hang with the Researcher app, which also redirects through the Wiley library system, I think.
Anyway, I hope this is enough information to maybe identity what’s going wrong here.
