Bitbucket login is leading to an infinite loop, not allowing access to the site

[City Form Lab]

Dear Atlassian support,

I can not access my bitbucket account and code repositories. The login screen leads to an infinite loop that spins between several login urls and never gets out. Please urgently help troubleshoot. My user email is asevtsuk[at]alum.mit.edu
