Unable to log into Bitbucket

[Dennis Meng]

Whenever I try to access the Bitbucket dashboard, I get a couple of redirects and then:

"You may run into this issue when you use specific browsers or add-ons that hide the referer header for id.atlassian.com and other Atlassian sites. Check for these and then try logging in again."

https://community.atlassian.com/forums/Bitbucket-questions/Unable-to-login-Bitbucket-We-couldn-t-log-you-in/qaq-p/1896018 makes it sound like my account needs reactivating (and it also said to post my case as a separate question)
