SSH pubkey works on Server, fails on Cloud

[Marakai]

I've been migrating my repos from my hosted Bitbucket Server to Bitbucket Cloud and for the most part it's been problem-free.

Except for one baffling issue:

I can no longer use Git ssh to pull/push my Windows based repos. I get the notorious message about invalid pubkeys, but with a twist.

First, needless to say, I copy-pasted the public SSH key into my Bitbucket Cloud Project. The SSH keys are called id_rsa and id_rsa.pub.

Some things I've tried:

• Push a branch from Windows machine to Bitbucket Server repo: WORKS (and has for years now)
• Push a branch from Windows machine to same repo now in Bitbucket Cloud: FAILS (pubkey is in place)
• Install the SSH keys on a Linux machine and clone and push the same repo to Bitbucket: WORKS (a new Linux account, so I wouldn't have any "lingering" SSH keys)
• Any repo I had moved from Server to Cloud but Linux-based: WORKS
• Mac OS build machine pulling the Windows repo via a Bamboo agent: WORKS (it's a Xamarin project developed on Windows for iOS/Android)
• As the SSH keys on Windows are on a file share/UNC drive, copied them to a local directory on Windows machine and pointed .ssh/config at them: FAILS (i.e. makes no difference where on Windows the key files are)
• Cygwin command line on Windows: FAILS
• Gitkraken GUI on Windows (with the SSH keys used): FAILS
• Gitkraken GUI on Windows (with newly created internal keys copied over to Bitbucket Server): FAILS
• MINGW window from Gitkraken on Windows: FAILS

In other words:

• Bitbucket Server Git ssh works and worked from Windows, Linux, MacOS
• Bitbucket Cloud Git ssh works only on Linux and MacOS and fails on Windows.

Just as icing on the cake, I did a

"ssh -Tv <myprojectaccount>@bitbucket.org"

and that works! I get a "can't SSH into this account" as expected, but I see the key exchange working just fine.

I'm pulling my hair out here!

None of the online solutions apply:

• I *do* have the public key installed
• The keys *are* working, but only in a certain combination as outlined above

Help!

Hey @Marakai,

Could you create a support ticket for this?

What you're describing sounds very strange, and a support ticket will help us make sure you get this resolved.
