When trying to login via browser, I go through the OAuth selections then am redirected to:

http://127.0.0.1:37125/?code=

Which the browser is unable to connect to.

error.log shows:

com.sun.javafx.application.PlatformImpl startup
WARNING: Unsupported JavaFX configuration: classes were loaded from 'unnamed module @378a34ab'

Though java is current per:

./update-component.sh java https://github.com/adoptium/temurin25-binaries/releases/download/jdk-25.0.3%2B9/OpenJDK25U-jdk_x64_linux_hotspot_25.0.3_9.tar.gz
============================================================
note: requested java version already exists, overwriting

Any ideas? Worked fine a month ago.
On fedora linux (current stable), installed using the automatic script.
FAF client version v2026.4.1

Thanks
