I'm going to assume, based on that port, that you're using the native git protocol on port 9418 instead of HTTPS or SSH - and that, therefore, you're using Bitbucket Server instead of Bitbucket Cloud. Either way, the git protocol is not supported (https://jira.atlassian.com/browse/BSERV-2508 for Server, https://bitbucket.org/site/master/issues/11899/not-able-to-use-git-protocol-url for Cloud).
Are you able to push/pull/clone/etc using HTTPS or SSH instead?
