Lauchner does not start update

Hello I’m new to the matter, I downloaded and installed the launcher.
I have switched off my firewall.
I have released various ports in Windows, but the launcher does not go beyond what is shown in the picture.
My English is not the best. Sorry for that.

I have uninstalled and reinstalled the launcher a few times, but nothing has helped.
I hope one of you can help me!
