Certificate error for bitbucket.org on chrome browsers
Incident Report for Atlassian Bitbucket
Between 2022-05-02 18:02 UTC - first customer report - and 2022-05-02 19:53 UTC some customers using the Google Chrome browser experienced certificate validation errors relating to certificate transparency logs for Atlassian Bitbucket - bitbucket.org. Atlassian had requested a new certificate from our provider as bitbucket.org was due to expire in a month - we are still investigating the root cause - a new certificate in the transparency logs causing Chrome to error out when given a valid bitbucket.org cert that is not the latest. We have deployed the new certificates ahead of time to mitigate the issue and have verified that customers are no longer seeing the errors.

As a workaround, try using a different browser.
