Bitbucker server Windows unable to add SSH key

[Arunas Bartisius]

Hello,

there is Bitbucket server running on Windows, and trying to add publick SSH RSA key, the error is showed:

You must enter a valid public key

Any suggestions?

As per documentation it should be straight forward https://confluence.atlassian.com/bbkb/invalid-ssh-key-610763481.html but it clearly states that this is for Bitbucket Cloud.

PS. the key is valid, can be used in other systems.
