Error: The host key is not cached for this server

I've followed all the steps regarding ssh key autentification between sourcetree and bitbucket but when i try to clone a repository i'm receiving the error bellow:

Command: git -c diff.mnemonicprefix=false -c core.quotepath=false --no-optional-locks ls-remote ssh://git@bitbucket.internal.xxxxxxx/xxxx/xxxx.git
Error: The host key is not cached for this server:
  bitbucket.xxxxxxxx (port 22)
You have no guarantee that the server is the computer
you think it is.
The server's rsa2 key fingerprint is:
  ssh-rsa 2048 SHA256:HsP+Q3P3v3TAK+tXRQ5T7XDGM7R/6iUVuqojC7hvHKA
If you trust this host, enter "y" to add the key to
PuTTY's cache and carry on connecting.
If you want to carry on connecting just once, without
adding the key to the cache, enter "n".
If you do not trust this host, press Return to abandon the
Store key in cache? (y/n, Return cancels connection, i for more info) fatal: Could not read from remote repository.


Can you please help me?

hey @adina-alexandra_Pinzaru 

Looks like you configured PuTTY as your ssh client for SourceTree.

Try launching PuTTY without SourceTree and run the command: ssh -T

It should ask you to verify the host fingerprint (as above) and you should enter `y`.

Once the fingerprint is saved, try re-launching SourceTree.

Hope that helps

it needs me to login?

@Erez Maadani Thank you, been busting my head over this!
