'How to use SSH connect Gitea and SourceTree?

now I long to build a private git server myself by gitea and use SourceTree as a git GUI (on Windows)

Current situation & steps:

1.I've already set up a host with gitea, and create a repos here.

2.I used SourceTree (putty) to create a public SSH key and save the .ppk file.

3.Adding this SSH on gitea page (something might be wrong because there is a verification button) SSH on gitea

4.Using Pageant.exe on client to add key

5.Using SourceTree and try to clone the new repos by SSH SSH url

6.However, SourceTree on Client can not recognize the url

enter image description here

note:

1.both two computers connect to Local Area Network

2.opening port:3000 on host is done, and using "telnet HOSTNAME 3000" on client is successful

3.error message when using git command is here error

Is there any step I did wrong?
