why error connecting to github from powershell command line?

Question

first time using GitHub.
Created the repository on github.com. Now I want to push to that repository. Getting "connection failed" error.

When I run "ssh -Tv [email protected]" I get "connection timed out".
And "ssh -T -p 443 [email protected]" fails with: Permission denied.

I turned off the windows firewall. Same error.

What to do? How to connect to GitHub?
I am using VSCode. Working from the powershell command line.

Here are the commands I tried:

    PS C:\gitsteve\maker> ssh -Tv [email protected]
OpenSSH_7.1p2, OpenSSL 1.0.2g  1 Mar 2016
debug1: Reading configuration data /etc/ssh/ssh_config

debug1: connect to address 192.30.255.113 port 22: Connection timed out
ssh: connect to host github.com port 22: Connection timed out

PS C:\gitsteve\maker> git push -u origin master
ssh: connect to host github.com port 22: Connection timed out
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.

PS C:\gitsteve\maker> ssh -T -p 443 [email protected]

some more info. the git push -u origin master command worked from the git shell of the github desktop app. — RockBoro

If SSH is blocked for any reason, try and switch to an https URL

 cd /path/to/repo
 git remote set-url origin https://github.com/<username>/<reponame>.git

Then try again

 git push -u origin master

Then first time, it should require your GitHub username/password (which has nothing to do with the passphrase you might have set on your private SSH key: it needs your GitHub account password)

If you have installed a Git credential helper (as in this answer), those GitHub credentials will be cached (meaning vscode won't ask you again for username/password at the next push)
Check first the value of git config credential.helper: if you see manager, you have nothing to do.
