20516	"SOCKS proxy without authentification demands ""credentials for host"""	hoverboard	team	"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 google.com
}}}

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 '/127.0.0.1:8080' for URI 'https://josm.openstreetmap.de/browser/trunk/nodist/images/download.png?format=raw' failed. Exception was: java.net.SocketException: Malformed reply from SOCKS server
}}}

I've patched JOSM to ''System.out.println'' my external IP through ""http://checkip.amazonaws.com"" 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?"	defect	new	normal		Core			socks proxy
