Steps to reproduce the behaviour

"Download Linked File" option on JabRef 5.4 works fine within the same corporate firewalled network environment and on the same Windows 10 computer.

1. Download and unzip JabRef 5.10 portable within a corporate firewall environment on Windows 10 computer, post install details as follows.
   JabRef 5.10--2023-08-07--3d197a9
   Windows 10 10.0 amd64
   Java 21-internal
   JavaFX 20+19

(NOTE: Same issue is also observed in admin install of JabRef version as follows.
JabRef 5.10--2023-07-18--34ac6d1
Windows 10 10.0 amd64
Java 21-internal
JavaFX 20+19)

2. Import SSL certificate within Preferences->Network. Use the custom proxy option within Preferences->Network.

3. Verify internet connectivity using the button in Preferences->Network. Confirmed that it works.

4. Go to Jabref WebSearch, choose ArXiv for searching. Search for "https://arxiv.org/abs/2307.14043".

5. Select "Download linked file" option in resulting search result and import the entry into bib file.

RESULT: The entry is imported but an empty html file is created instead of downloading actual pdf from ArXiv website.
