Solution 1:

Add the absolute file path to a custom SSH config file(C:\Users\{USERNAME}\.ssh\config), and my problem is solved.

Solution 2:

If you format/re-install Server OS, but use same IP as before, you may encounter fingerprint mismatched.

You may need to delete old fingerprint in this file: C:\Users\xxx.ssh\known_host

and old IP in the file: C:\Users\xxx.ssh\config

Then try to add host again.

Solution 3:

What worked for me:

1. delete ssh config folder both in C:\Program Data\ssh and C:\<user>\.ssh
2. In VS Code, press F1, choose Remote-SSH: Connect to Host...
3. Do NOT enter anything in the prompt, but instead choose + Add New SSH Host..
4. Enter the full ssh command, including the key (in case of Windows, you may want to enclose the path with double quote mark) ssh -i "C:\path\to\key" user@host. (you need to make sure the key has a limited permission. Remove all inherited permissions, and only give a full control to the owner.)
5. You will be asked to choose a folder in which a new config file will be created. Choose any of the two options.
6. There will a prompt notifying that the new config file has been created. Click connect

Solution 4:

What worked for me was to delete all of the contents of folder: C:\Users\MYNAME.ssh That meant to delete both the config file and known-hosts. The config was probably the most important one to delete.
