Curl: (52) Empty reply from server Ubuntu curl -i http://localhost:8001/

Hello Friends, install Kong 2.8 on ubuntu 22.04 I followed the instructions from the official site Install Kong Gateway on Ubuntu - v2.8.x | Kong Docs
I configured it with PostgreSQL, migrations worked perfect
I start the service with:
sudo kong start -c /etc/kong/kong.conf … and it says Kong started.
sudo kong health … says nginx…running.
Kong is healthy at /usr/local/kong
but curl -i http://localhost:8001/ tells me
curl: (52) Empty reply from server

Can anybody help me :frowning:
