I was trying to set up the library proxy connection (under setting -> proxy access). When I test the connection, I got the following message, although I already logged in:
Connection to "Princeton University" failed. Make sure you are logged in. Log in
If I click log in again, it was successful:
Authentication for "Princeton University" was successful
I can then test the connection again, but it still fails. Any clue how to fix it? Thanks in advance!
