Install script "script.deb.sh" Failed to connect

Hello!

When I run the script “script.deb.sh” I get the following error message:

root@dev:/home/luigdima# curl https://packages.gitlab.com/install/repositories/gitlab/gitlab-ce/script.deb.sh
curl: (7) Failed to connect to packages.gitlab.com port 443: Expiró el tiempo de conexión

My DNS server is functioning properly, but is not able to connect with “gitlab”.

My version 7.35.0
