Cannot import to Zotero through proxy

I am trying to import the following article:
https://doi.org/10.1002/smtd.202401773

When using the proxy, it is on the following page:
https://onlinelibrary-wiley-com.insis.bib.cnrs.fr/doi/full/10.1002/smtd.202401773
https://s3.amazonaws.com/zotero.org/images/forums/u265723/kfehf2plyygyencd3s1b.png

But the connector fails with the following error:

Zotero Connector: 5.0.196beta3

When I disable the proxy, the connector is working fine, but I do not have access to the PDF file anymore:
