testing – Bitcoin core functional tests failing running on WSL2 on Windows 10

I am running this command (using a 4GB temp HD mounted):

# test/functional/test_runner.py --cachedir=/mnt/tmp/cache --tmpdir=/mnt/tmp

And for all tests I get this errors:

mempool_accept.py                          | ✖ Failed  | 6 s

Then I got this first file to test:

feature_fee_estimation

And only for it I got this error:

I also changed my /etc/resolve.conf to this, but no success:

search localtest.me
options ndots:15
nameserver 8.8.8.8
nameserver 8.8.4.4

What else can I try to make all tests work? Thanks
