I am attempting to push a git repo to github with ssh. I can authenticate but I cannot push.
I am using a ssh key called ssh_key_test1 and this gets employed when on Powershell when I run ssh -vT [email protected] I get

Hi eliseodifolco! You've successfully authenticated, but GitHub does not provide shell access.
debug1: channel 0: free: client-session, nchannels 1
Transferred: sent 4084, received 3632 bytes, in 0.2 seconds
Bytes per second: sent 17622.1, received 15671.7
debug1: Exit status 1

but then when I try

git push -u origin HEAD:main

I get permission denied

[email protected]: Permission denied (publickey).
fatal: Could not read from remote repository.

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

running

git remote -v

shows that the relevant origin is picked up

origin  [email protected]:eliseodifolco/api_test.git (fetch)
origin  [email protected]:eliseodifolco/api_test.git (push)

could it be that the ssh service finds the relevant key only for some commands such as ssh -T [email protected] which is successful?
