SSH: Build-in OpenSSH
I tried to connect my Ubuntu server(18.04) by using my PC(Windows), but it doesn't work!
It shows sh_dispatch_run_fatal: Connection to 192.168.43.206 port 22: Permission denied
This is the log but I can't understand it, why was permission denied?

I have an issue when I can't ssh to our company GitLab server,
I can easily push, pull, clone repo from this server but when I try to ssh I get an error,
I'm trying to do that on Ubuntu VM and my windows desktop, on both I can do everything except ssh to the server. I can easily ssh to some other servers like Acquia with the same key.
Appreciate any help

oskar#gitlab.test-test.com: Permission denied (publickey,gssapi-keyex,gssapi-with-mic).
Note i changed some unnecessary details for security
I can easily push, pull, clone repo from this server
Make sure you can do so using an SSH URL, not an HTTPS one.
If you do use an SSH URL when (successfully) cloning your repository, repeat, for testing, a clone with:
git -c core.sshCommand="ssh -Tv" clone git#gitlab.test-test.com:...
That will show you what file is actually used.
Don't forget that, contrary to your logs (which shows oskar#gitlab.test-test.com), an SSH is always done using the service account git, not your own login name.
If you tried ssh oskar#gitlab.test-test.com, I confirm it will never work: there is no oskar on the remote server, only the technical service account git (which, in turn, has an ~git/.ssh/authorized_keys with your GitLab ID associated to your public key: that is how GitLab authenticates you).

I think the error started to show up after system update. How to fix this seteuid invalid argument error? I event tried downgrading the openssh server; it to throwed same error. How can I fix this?
Windows 10.0, Build 18363
I have deleted the initial user with which i've installed cygwin. Deleting all cygwin files and registry entries and reinstalling cygwin fixed the issue. I wish I knew exactly on what files i have to change user permissions. I hope someone answers it.
I've tried following solutions, so I did generated new ssh key for my gitlab account, when I do ssh -v git#gitlab.com I've got Permissions denied (publickey)..
Second solution is Working with non-default SSH key pair paths, so I've generated new key for that and my ~/.ssh/config is looking like this
# GitLab.com server
Host gitlab.com
RSAAuthentication yes
IdentityFile ~/.ssh/id_rsa_gitlab.pub
Both key's are added to my gitlab account, and when I try to troubleshoot ssh with:
ssh -i ~/.ssh/id_rsa_gitlab.pub -p 122 git#gitlab.com I've got nothing, literally when I type that to the terminal nothing is happening, and when I type shh -vvv git#gitlab.com the result is this:

Can someone please explain me how to fix this?
The IdentityFile should point to the private key, not to the public key:
IdentityFile ~/.ssh/id_rsa_gitlab
As #Jakuje suggested I was making a mistake in IdentityFile, but also I didn't know that this gitlab is staged on a private server so, if you want to clone a repository from private gitlab you need to do this
git clone git#ip_address_of_the_server:SomeName/ProjectName.git and you will be able to successfully clone the repository, but you first need to add ssh key to your gitlab profile.
You can also git clone it using http, then you need to do this
http://server_ip_address/SomeName/ProjectName.git, and you will be prompt for your username and password.

I've been trying to connect to my running instance for a while now and nothing is working, I tried generating a public key and importing it. that didn't work.
Then I downloaded the .pem file from aws. But it always asks me for a passphrase everytime, then tells me passphrase is invalid. I've googled and tried everything I've seen on the internet but none of them are working for me.

Please help, I've been at this for an hour now. I have experience with how ssh keys work as I've used digitalocean before but I'm a beginner with AWS and this is very frustrating.
If you get prompted for the password of a .pem file and you know that there is no password on the key, it's normally an indication that ssh can't read the file properly.
I've seen this happen when somebody did a Copy & Paste and had incorrect linebreak characters.
If you open the file in a text editor, the lines should all be of the same length except the last one, with headers like this:
-----BEGIN RSA PRIVATE KEY-----
MIIEowIBAAKCAQEAgERw9liYOkOAPNrnupzGEMA9dLTIKmSp98F4eveqLq3WH9sIc2FZpzGT3HEm
qBFGvNkgywPZommXsamZ53mt3KJ1FTAZ5roojScbjawzjg5B+JhRHpj6bVDapSZl1bM0CQPLxWK2
LbvBHjfXtFJEndxPk7PQxSnYsvOqwpdggWPwLmbpyadmzdfrpCcCgYEAm3U6jhReSOqDbEG8gAMi
...
8VVrSccLeNVP2KapL6VsXO6lZmuCgz0B9RghrO+CQ/4okoZO53wc+UdJkLX9s5d+gaR3
-----END RSA PRIVATE KEY-----
If the file looks different, try to obtain another copy of the key.
