Can't clone repository using SourceTree

[Ukraine_eagle]

Hi there! I settuped SSH keys connection using this link

https://support.atlassian.com/bitbucket-cloud/docs/set-up-ssh-with-sourcetree/

But when i'm trying to clone my repository i recieve this error

Команда: git -c diff.mnemonicprefix=false -c core.quotepath=false --no-optional-locks ls-remote git@bitbucket.org:nikotribe/bufftokill.git
Вывод:
Ошибка: The host key is not cached for this server:
bitbucket.org (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:zzXQOXSRBEiUtuE8AikJYKwbHaxvSc0ojez9YXaGp1A
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
connection.
Store key in cache? (y/n, Return cancels connection, i for more info) fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.

Please help me. Thank you
