I carefully follow official [documentation](https://docs.gitlab.com/ce/ssh/README.html) how to connect to self-hosted GitLab from Windows (tried with VisualStudio and Tower).  

But connection is not established.

From [Troubleshooting](https://docs.gitlab.com/ce/ssh/README.html#troubleshooting) section I run `ssh -Tv git@gitlab.mydomain.com` and get this:

It outputs

, but my id\_rsa.pub exists:

[![file](https://i.stack.imgur.com/u1LQp.png)](https://i.stack.imgur.com/u1LQp.png)

I added my public key to my profile in GitLab: `cat ~/.ssh/id_rsa.pub | clip`. 

My repository https url is: `https://gitlab.mydoamin.com:3000/web/oppis.git` and it works (not sure if port matters), but not with SSH.

**Edited:**  

I know path is strange for Windows environment, but I don't know how to fix this. Also when executing `ssh-keygen -t rsa -C "your.email@example.com" -b 4096` suggested path for saving keys are "strange": `/c/Users/matjaz.cof/.ssh`, but files are saved. So I though this should work.

**Edited** @JuanMellado

I found something strange:

```
debug1: Offering public key: RSA SHA256:w3E6UGqM5x3VniG+sKMxOJiTupmX3N4pwWPt6PW9di8 /c/Users/matjaz.cof/.ssh/id_rsa

debug3: receive packet: type 51
debug1: Authentications that can continue: publickey,password
debug1: Trying private key: /c/Users/matjaz.cof/.ssh/id_dsa

```

Strange is I have `id_rsa.pub` and `id_rsa` files. (They were create with GitBash `ssh-keygen -t rsa -C "your.email@example.com" -b 4096`)

So I change `id_rsa.pub` to `id_rsa` and `id_rsa` to `id_dsa`.

Now I get different log (relevant section):

```

Not sure why it tries to send another private key (`id\_ecdsa)?

Strange is that `/c/Users/matjaz.cof/.ssh/id_rsa` is not found, but `/c/Users/matjaz.cof/.ssh/known_hosts` is.  

I have 3 files in `c:\Users\matjaz.cof\.ssh\`:
