Someone has already added that SSH key.

[AlexEdimensionz]

I Tried adding my SSH key to my account

I get the "Someone has already added that SSH key." message. But I can't find out which account added it. I tried all my email addresses, but i can't find another registered account that I have.

Logging in via SSH using the instructions in the community form, I see the following message 

"authenticated via ssh key.

You can use git to connect to Bitbucket. Shell access is disabled"

G'day Alex!

Welcome to the Bitbucket Cloud Community! :) 

So that we may proceed with investigating this for you - are you comfortable sharing just your public SSH key here that you are trying to use? I can look this up in the backend and find which workspace this belongs to, if not let me know and I can raise a support ticket on your behalf.

Cheers!
