My server doesn't show up on doomlist.net but it shows on doomseeker master server.

Some months ago my public server won't show up on doomlist.net but it shows up on my doomseeker server list. I thought there's no problem and told my friend to join in, but he can't find my server. I just checked now again to see if this still happen and it did. Can someone tell me how to fix this?

DoomList only implements the old protocol which will be replaced with the new protocol once 3.2 releases. The reason the old protocol is being replaced is because of this: https://zandronum.com/tracker/view.php?id=4064
I suspect your issue is related to this, where the server transmits too much data and this simply cannot be handled by the browser.
