Can you connect before or is-it your first attempt?
You can test with ssh directly : ssh --vvvT <your gitlab url>

git error
While trying to connect to gitlab I get this error meesage:
ACER@DAVY MINGW64 /e/xampp76/htdocs/Fashionblinds/Fashionblinds (master) $ git push origin master The authenticity of host 'gitlab.com (172.65.251.78)' can't be established. ECDSA key fingerprint is SHA256:HbW3g8zUjNSksFbqTiUWPWg2Bq1x8xAAEEiXFzSnUw. Are you sure you want to continue connecting (yes/no/[fingerprint])? yes Warning: Permanently added 'gitlab.com,172.65.251.78' (ECDSA) to the list of known hosts. ssh_dispatch_run_fatal: Connection to 172.65.251.78 port 22: Broken pipe fatal: Could not read from remote repository.
Please make sure you have the correct access rights and the repository exists.
What should I do ?

I thought my Windows Credential Password to Gitlab is already correct!

To this particular gitlab project is the first time. I have used gitlab before for other projects.

This is what I got how to troubleshoot the error message ?
See I cannot find .gitconfig or .config/git/config file
I can only found .git folder in my laravel folder that I would like to push to the server.

It seems there is an error in the gtilab doc, you have to test with
ssh -T [email protected]
it returns for me : Welcome to GitLab, @sr57!
If works by finding key in your .ssh directory, key that you must have put in gitlab before.
If it does not work for you, share the returns of the command :
ssh -vvvT [email protected]

Where is the .gitconfig and .config/git/config file ?

HI @davy_yg
Communication is always a difficult art, just enter the commands
ssh -T [email protected]
ssh -vvvT [email protected]
remove the end :davy_yg/fashionblind.git it's not a valid address as the error tells you.

This is what I got. What does it means ?
Level 39
Have a look to these messages : Trying private key
ssh does not find your key (not created, deleted, in another directory).
If you don't know* where your key is, the easiest way is to rereate one ( for instance : ssh-keygen -t rsa -b 2048 ) and then copy the pubic key in Gitlab. Follow the doc https://docs.gitlab.com/ee/ssh/
*No pb if you had not use these key for another usage,, if not, you lost other connection(s) and worse if for any reason you publish somewhere your private key.

When I try to add the key there is this questions:
Oops, are you sure?
Publicly visible private SSH keys can compromise your system.
[Yes, add it ]
Also there is this old key:

(I already changed the key for security purposes)
Should I keep the old key ?
The form contains the following errors:
Key is invalid
Fingerprint has already been taken
Fingerprint cannot be generated
Key type is forbidden. Must be RSA, ECDSA, or ED25519
This error appears when I tried to save it.

What don't you understand in my answer, following the doc, to put a key in gitlab is just a copy/paste of your key!
Do you really think your answer is the best?
Level 27
I have copy and paste the key repeatedly but copy and paste the wrong key. Until I found the video then I found the solution.
