Well, as Stu points out, something is wrong that causes sdr.hu to see registrations packets coming from a public ip address that does not resolve to the same ip as the domain you're attempting to register with. They should match. It doesn't matter if that's a "household" public ip address or one on the end of a tunnel or proxy.

v1.258 is out with TDoA UI and reliability improvements:

v1.257, 258  January 9, 2019
    TDoA UI improvements:
        Added "4" button to zoom buttons at upper left. Zooms directly to level 4.
        Shift-clicking on the +/- buttons zooms by 3 levels instead of just one.
        Added distance scale (in km/m & miles/feet) to map at lower right.
        Added ruler function. Click on the "protractor" icon at lower right. Mouse cursor will
            change to cross symbol. Click on starting map position. Move mouse to ending map
            position and double-click to end ruler measurement. Or single-click to make
            intermediate measurement and continue. Click on icon to clear measurement.
            Don't use escape key as that will close the extension! (this may be fixed in the future)
    
    Admin GPS tab: now says "loading maps..." when display delayed due to map download process.

    By request: URL parameter "no_geo" to disable browser from determining and sending Kiwi the
        geolocation information of the connecting user.
        Use like other URL parameters, e.g. "mykiwi:8073/?f=5Mam&mute&no_geo"
        This will someday become one of the "user preferences" options.

Not sure what's wrong there. One of my browsers shows the pdf in that thread fine and the other doesn't. Here it is again:

Christoph has identified the issues necessary to make 20 kHz Kiwis work with TDoA (in principle at least). One issue was implemented in v1.252/253. Others to follow as time permits.
