Local Git cannot resolve hostname with "ssh://" in the config, and asking for password without

Question

I'm struggled with my new Gitlab server (version 12.10.3) and my local git project: I am trying to import it, however I'm stuck with the remote URL settings.

With the following URL, git asks me a password:

git remote set-url origin git@192.168.1.20:mygroup/data/myproject.git
git push --all
git@192.168.1.20's password:

To avoid that, I've red in a different topic that I need to add ssh:// at the beginning of the URL to make this working, and then:

git remote set-url origin ssh://git@192.168.1.20:mygroup/data/myproject.git
git push --all
ssh: Could not resolve hostname 192.168.1.20:mygroup: Name or service not known
fatal: Could not read from remote repository.

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

Of course, the IP address is reachable when I do a ping from my workstation. I've also setup my SSH key, added it to my Gitlab account, and added the gitlab's public key in the known_hosts folder:

ssh-keyscan 192.168.1.20 >> /c/Users/MyName/.ssh/known_hosts

Did I missed something?

EDIT

Looks like there is potentially an issue with my SSH key. I've tried to debug it with ssh -Tvvv git@192.168.1.20, and I've got the following output:

git@192.168.1.20's password:

It seems it used the certificate authentication process. My key in /c/Users/MyName/.ssh/id_rsa has been used to authenticate, but for some hidden reason, it didn't worked.

I've checked again on Gitlab SSH keys section, and the key is exactly the same as expected.

git remote set-url origin git@192.168.1.20:mygroup/data/myproject.git
git push --all
git@192.168.1.20's password:

I've also setup my SSH key

Well, looks like you didn't. To verify it start debugging with ssh -Tv git@192.168.1.20.

git remote set-url origin ssh://git@192.168.1.20:mygroup/data/myproject.git

The correct SSH URL syntax is ssh://[user@]host.xz[:port]/path/to/repo.git/. See the different syntax in the docs.

In your case the URL should be ssh://git@192.168.1.20/mygroup/data/myproject.git. The path isn't separated with :, it's started with /. A colon is used to separate host from the path only in scp-like syntax [user@]host.xz:path/to/repo.git/.
