Wrong IP number showing on Doomseeker

[joseluisdacruz]

Running the following command:
flatpak run --command=zandronum com.zandronum.Zandronum -connect '192.168.0.109:10667' -iwad '/run/user/1000/doc/f69966c/iwad-master/doom2.wad'
Doomseeker displays wrong IP number (clipboard copy):
/app/bin/zandronum -connect '::ffff:192.168.0.109:10667' -iwad '/run/user/1000/doc/f69966c/iwad-master/doom2.wad'
No one can connect to my game from Doomseeker. I can connect if I run the following on terminal:
flatpak run --command=zandronum com.zandronum.Zandronum -connect '192.168.0.109:10667' -iwad '/run/user/1000/doc/f69966c/iwad-master/doom2.wad'
