SSH on Port 443

[alondono]

This question is in reference to Atlassian Documentation: Use the SSH protocol with Bitbucket Cloud

When I try to use port 443 as is suggested at the end of the article (when port 22 is blocked), I get the following message:

The authenticity of host '[altssh.bitbucket.org]:443 ([104.192.143.16]:443)' can't be established.
RSA key fingerprint is SHA256:zzXQOXSRBEiUtuE8AikJYKwbHaxvSc0ojez9YXaGp1A.
Are you sure you want to continue connecting (yes/no)?

I can continue, apparently without issues, but is that ok?

What do you think ?

Excerpt from docs:

The first time you access Bitbucket using the SSH URL, your SSH client checks to see if the Bitbucket host is a known host. If the host is not in your ~/.ssh/known_hosts file SSH warns you that it is adding the Bitbucket host to known hosts:

You should also notice that zzXQOXSRBEiUtuE8AikJYKwbHaxvSc0ojez9YXaGp1A does not look like your toe fingerprint. No curls there.

OK, I see what you mean. Thank you. I am very new to this.
