Can'；t与gitlab建立ssh连接

我在gitlab上有一个项目，我正试图推动一个承诺。我首先用https url克隆了该项目，但随后将其更改为ssh，然后运行

cat~/.ssh/id_rsa.pub

，它为我提供了ssh密钥：我已将密钥复制粘贴到gitlab配置文件中的ssh密钥，但在尝试推送提交时，我收到一条消息：

无法建立主机“gitlab”的真实性。RSA密钥 指纹是SHA256:cZiqgz2tMzLXftNIIXmQ9v+6M38xM1LzxROnDM1OJ0Q。 是否确实要继续连接（是/否）？对 警告：已将'07.no'，myIpAddress'（RSA）永久添加到已知主机列表中。 权限被拒绝（公钥）

在运行

ssh-Tv时git@myEmail

debug1:SSH2_MSG_KEX_DH_GEX_请求（2048它告诉您以前从未连接过此服务器。如果您希望这样，这是完全正常的。如果您患有妄想症，请使用备用通道验证密钥的校验和/指纹。（但请注意，可以重定向ssh连接的人也可以重定向web浏览器会话。）

如果您在此ssh安装之前已连接到此服务器，则可能是服务器已使用新密钥重新配置，或者有人正在欺骗服务器的身份。由于中间人攻击的严重性，它会警告您这种可能性

无论哪种方式，你都有一个安全的加密通道，没有指纹对应的私钥，任何人都无法解码你发送的信息

您用来对自己进行身份验证的密钥是不相关的……您不会希望将身份验证信息发送给可能会窃取它的欺诈服务器，因此您不应该期望根据您是要使用密码短语还是私钥登录而发生任何更改。您只是在这一过程中还没有走那么远。
是的，我没有以前尝试过连接，这是我第一次，但是，我无法推送任何东西，因此，我如何修复它？好的，它会警告您正在连接的新主机，因为@Rohit Poudel回答正确，但在您的编辑中还显示“权限被拒绝（公钥）”这表明GitLab无法识别密钥。您确定repo在您的用户帐户下，您可能也在其中添加了SSH密钥吗？另外，如果您运行
git remote-v
，它是否显示：
