Failed to request file info from nexus

[GiovanH]

The problem:

Opening Nexus links in MO2 always fails. The log shows an empty request body.

Issue persists after clearing the cache, reauthenticating, reinstalling MO2, etc.

Nexus mods download as expected via "manual download" and MO2 is able to check for updates, so it shouldn't be an auth issue.

Happens with multiple game profiles.

Environment:

• Mod Organizer v2.5.2
• Windows 10

Without changing anything, I've now become able to sometimes download nexus links. Still a bit flaky though.
