SOCKS proxy without authentification demands "credentials for host"

Reported by: hoverboard Owned by: team
Priority: normal Milestone:

Keywords: socks proxy Cc:


I'm using a SOCKS proxy on localhost:8080 without authentification.

On JOSM startup it demands "credentials for host" while building the main window.

But the proxy works:

curl --socks5 localhost:8080

Then I press "Authentificate" (or 2x "Cancel" – works also!) and the GUI finishes.

When canceling instead of authentificating, this error message follows:

2021-02-20 22:09:39.236 SEVERE: Connection to proxy '/' for URI '' failed. Exception was: Malformed reply from SOCKS server

I've patched JOSM to System.out.println my external IP through "" to verify that the IP is not my home IP.
And then everything works over the SOCKS proxy: Downloading imagery tiles, uploading to the API, ...

Is JOSM unable to probe a SOCKS proxy without authentification?
