Request header is too large

Frequently getting this error when trying to use Endnote click to download articles from pubmed though my institution. Not sure if the error is with endnote click or the institutional access.

HTTP Status 400 – Bad Request

Message Request header is too large

Description The server cannot or will not process the request due to something that is perceived to be a client error (e.g., malformed request syntax, invalid request message framing, or deceptive request routing).
