Can't push after changing username

I changed my username from AdamKG to adamkg in order to try the static hosting, however, I can't seem to push anymore:

Per
https://bitbucket.org/site/master/issue/412/ability-to-change-username-with-openid#comment-6360 I removed & re-added my SSH key, but it didn't change anything.
