dns on android could be broken. just because you can do a dns from a desktop / laptop doesn’t mean it resolves the same way on your android device (i.e. bugs in android dns resolution) I might experiment by installing and activating this https://github.com/x-falcon/Virtual-Hosts/ (though wont appear in the leanback launcher, have to jump through hoops to run) this might intercept the dns requests and have them be resolved in a manner that works.
