Telnet gitlab.com 443 is passed. But still doent opening website

Seems like gitlab blocked me. When I make telnet gitlab.com it connects. But when i curl https://gitlab.com it doesnt work

A few wide questions:

What error do you receive when performing the curl? Could you share your output of a verbose attempt (curl -v https://gitlab.com)?

What are you specifically observing when you say “doesn’t open website” / “doesn’t work”?

Does your environment use a HTTP/HTTPS proxy that controls outbound traffic? If yes, is GitLab.com configured within its whitelists by its administrators?
