[X] I have tested the latest development version and the problem persists

Steps to reproduce the behaviour

I'm using JabRef behind my organization's proxy.

Running ./JabRef --debug --nogui --fetch=Crossref:"Representation independent algorithms for molecular response calculations in time-dependent self-consistent field theories" from CLI, it returns

I understand that Proxy returns "HTTP/1.1 403 Forbidden" sounds like a problem of the proxy server itself. I can, however, get the json from https://api.crossref.org/works?query=Representation+independent+algorithms+for+molecular+response+calculations+in+time-dependent+self-consistent+field+theories in my browser or CLI (curl/wget). For example, with wget

Setting proxy maunally in the preference doesn't do anything. In fact, setting the proxy or not, the Check connection button returns success.
