For better visibility, setting this to Core: Networking DNS. If this is not the right component, please assign a more appropriate one. Thanks!

This seems o be fixed by bug 1899841 and I also can't reproduce this with 128.0a1 (2024-06-07).

Could you verify?

Sorry, I was wrong.
The real problem seems to be that the TRR URI is not correct. It should be https://9.9.9.9/dns-query.

Could you try to set the TRR URI to https://9.9.9.9/dns-query and test again?
Thanks.
